A Connecticut restaurant owner is claiming that Yelp deleted positive posts about her eatery after she refused to purchase advertising from the consumer reviews website.

Kelly Calandro, co-owner of Verace restaurant in Shelton, Conn., said positive reviews about the business started disappearing shortly after she told a Yelp sales rep that she wasn’t interested in advertising on the site, WFSB reports. The sales rep continued calling, and Calandro claims each time she refused to buy ads, more reviews went missing.

“In an economy like this, no business can afford to have something negative about them out there,” Calandro told WFSB.

Calandro is not the first to claim that Yelp removes reviews of businesses whose owners refuse to buy ads. In 2009 and 2010, the company was hit with several class-action lawsuits alleging such unfair business practices. One Oakland, Calif., newspaper even claimed in 2009 that the then five-year-old startup was in the business of “Extortion 2.0.”

But two years later, nearly all the lawsuits had been thrown out in court.

Yelp has said its site uses an "automated review filter" that protects users from fake or malicious reviews. The filter, which determines which reviews will be displayed on any given business page, applies the same set of rules for every enterprise profile, the company claims. To increase transparency, in 2010 Yelp introduced a feature that lets businesses see the reviews that have been removed by the filter.

“There has never been any amount of money you can pay Yelp to manipulate reviews,” Yelp spokeswoman Kristen Whisenand said in an email to HuffPost.

Yelp’s filter “is not a perfect system -- after all, legitimate reviews sometimes look questionable, and questionable reviews sometimes look legitmate -- but we think it does a pretty good job,” Whisenand added, citing a 2011 BusinessWeek article about the company’s efforts to beef up its detection of fraudulent reviews.

  • $100 For A Bedtime Tuck-In

    Ever wanted to be tucked into bed by a stranger? Probably not, but if you did, there's a Groupon for you. The Chicago-based offer describes, in detail, how Groupon employee Ben Kobold will tuck you in. "Ben's sinewy, well-groomed fingers delicately raise each sheet and blanket over your body until you're comfortably bundled," <a href="http://www.groupon.com/deals/ben-kobold-tuck-in" target="_hplink">the offer reads</a>. "Careful not to disturb any children who may be in the adjacent room, Ben leans in and uses his summer-breeze-like voice to gently sing you one of the five lullabies he has authored." Four people bought the <a href="http://articles.chicagotribune.com/2012-06-04/business/sns-rt-us-groupon-tuckinbre85315v-20120604_1_groupon-stock-ceo-andrew-mason-ipo" target="_hplink">actually serious deal</a>, which is <a href="http://www.groupon.com/deals/ben-kobold-tuck-in" target="_hplink">no longer available</a>.

  • 54% Off Breast Implants in Paris

    If there's anything you wouldn't want to have done on the cheap, it might be plastic surgery. But last July, a Paris Groupon offered breast implants for 54 percent off. "New! Finally treat yourself to the chest of your dreams for 2,499 euros instead of 5,430 in a private plastic surgery clinic; pay in two installments," the offer read. At least <a href="http://www.hauteliving.com/2011/07/groupon-breast-implants/" target="_hplink">three people bought the deal</a>. A <a href="http://www.guardian.co.uk/media/2011/nov/23/groupon-cosmetic-surgery-ad-banned" target="_hplink">similar deal</a> was offered in the U.K.

  • 76% Off Circumcision

    Much like breast augmentation, circumcision is another procedure for which you probably shouldn't be bargain hunting. But Groupon in the Philippines is offering just that, with <a href="http://www.beeconomic.com.ph/deals/metro_manila/Cosmedics-Treatment-Center/716084137" target="_hplink">76 percent off on a circumcision procedure</a>. The only thing creepier than paying a steep discount on your child's circumcision is the playfulness of the deal's description: "Just like a triple backflip, performing a circumcision on oneself requires a lot of mental preparation, is very risky, and cannot easily be repeated. Have a trained professional snip the tip with today's Groupon."

  • $1,000 To Name Your Baby Clembough

    Having trouble thinking of a baby name but have $1,000 to spare? Groupon thinks they have you covered: "A rose by any other name would smell as sweet, but a baby that isn't named by Groupon smells like missed opportunity." For that $1,000, the site will name your baby "Clembough." <a href="http://www.huffingtonpost.com/2012/06/11/groupon-will-name-your-baby-clembough_n_1586223.html?utm_hp_ref=mostpopular#slide=1008896" target="_hplink">Half-publicity gimmick, half serious deal</a>, a Groupon representative insists in the deal's Q&A that "this is the most serious deal that Groupon has ever seriously run in its serious history." <a href="http://www.groupon.com/deals/groupon-babyc" target="_hplink">The deal is still available</a>.

  • $25 Jeffery Dahmer Tour For Two

    <a href="http://crime.about.com/od/serial/a/dahmer.htm" target="_hplink">Jeffery Dahmer's crimes</a> -- murder, cannibalism and necrophilia of 17 young men between 1988 and 1991 -- are the kind of horror reserved for serial killer infamy. For anyone curious to see the streets and watering holes of Milwaukee where Dahmer stalked and picked up his victims, Groupon offered a $25 tour for two. However, after <a href="http://www.cbsnews.com/8301-504083_162-57389622-504083/walking-tour-of-jeffrey-dahmers-neighborhood-spurs-controversy/?tag=mncol;txt" target="_hplink">families of Dahmer's victims called</a> the deal insensitive, the <a href="http://news.cnet.com/8301-17852_3-57390038-71/groupon-advertises-jeffrey-dahmer-deal-then-kills-it/" target="_hplink">deal was shut down, after 15 purchases</a>.

  • The Luxury Las Vegas Bus That Never Showed

    Sometimes a deal on Groupon is too good to be true, as was the case for Southern Californian residents who bought round-trip "Luxury" tickets to Las Vegas. The deal was offered for $55, down from $149, and promised a "luxury bus" with free WiFi, premium movies, snacks and an unlimited drinks option. <a href="http://overheadbin.msnbc.msn.com/_news/2011/09/23/7922458-groupon-gone-bad-daily-deal-strands-passengers?lite" target="_hplink">MSNBC reported</a> that some luxury buses came up to five hours late, while some never came at all. A month later, Groupon severed ties with LUX over the fact that the company wasn't providing satisfactory service. Groupon <a href="http://www.10news.com/news/29779701/detail.html" target="_hplink">canceled the deal and refunded the passengers' money</a>.

  • Kink.com Adult Film Studio Tour

    Earlier this year, Groupon found itself in the crosshairs of an anti-pornography group's war on smut after <a href="http://www.huffingtonpost.com/2012/04/24/groupon-kinkcom_n_1450015.html" target="_hplink">offering a tour of Kink.com's headquarters in the historic San Francisco Armory Building</a>. Kink is the world's largest producer of fetish pornography, producing films that frequently feature BDSM. The tour included <a href="http://www.huffingtonpost.com/vanessa-pinto/touring-the-armory_b_1454704.html" target="_hplink">a look at the building's historical features</a>, as well as a look into Kink's film sets, prop rooms and production facilities. Some <a href="http://maybemaimed.com/2011/05/02/my-unreal-experience-on-the-kink-inc-armory-tour/" target="_hplink">champion Kink as an advocate of alternative sexuality</a>, while <a href="http://www.youtube.com/watch?v=33iKp_dK2IA" target="_hplink">others see Kink as providing a degrading form of "torture porn."</a> Groupon defended Kink and the deal, which is no longer available after selling over 1,000 coupons.
