There needs to be this list of businesses to give good reviews to on here. Yelp is now the 33rd most popular website in the US according to Alexa. Yelp has become a big player as far how much money local businesses get. I say screw them. Every business gets irrational dumbasses nowadays who threaten bad reviews if you don't give them free stuff. Now as for beating the Yelp filter, what would you do if you were Yelp and wanted to stop reviews? First you'd look at a ton of things from real reviews and fake reviews and try to find something statistically different probability wise. Yelp definitely looks at IP Address, what links you click on, how long you stay on each page, how long your reviews are, what kind of words you use, what time of day you leave reviews and log in, whether or not you leave a review when you log in, geolocation and IP netrange of the times you logged in with, screen resolution, etc etc... The reason why they've filtered out your reviews is because your statistically out of the norm probability wise. The average Joe doesn't login their Yelp account from Comcast, Verizon, Cox, Time Warner, and Cable vision from five different computers for the five times they've logged in. They also don't usually quit yelp after leaving a review for one company. If a company with 35 reviews has 30 reviewers who've no longer use Yelp right after leaving a review, that also raises a red flag. Bottom line is that it's harder to generate fake reviews than you think. So Yelp not only checks the reviews that the person left, but also the reviews the company receives. If a company receives more reviews between the hours of 2-4pm, higher than the statistical average of all the reviews on Yelp, that also raises a red flag. The solution is to have a list of businesses to give good reviews to, since we all got different IPs, screen res, and everything else to not stand out.
