Avoidr uses Foursquare to help you dodge your enemies

Foursquare is awesome for figuring out where your friends are, but it can also be useful for knowing where your enemies aren't. Avoidr, a service built on Foursquare, promises to help you "keep your friends close and your enemies at that bar down the street."

With Avoidr, you can select any Foursquare contact and discreetly declare him or her "dead to you." You also get to assign an insult to the person in question, picking from a list that includes everything from the tame "jerk" to the much more serious "cancer" or "douchelord." Once you've decided who you're avoiding, one click will tell you where NOT to go before you head out for the night.

Of course, this is only useful if you have a lot of enemies. If you just have one person to avoid, it's simple enough to pop open Foursquare and see where you don't want to be. Like PleaseRobMe, which points out Foursquare security issues by showing who's not currently at home, Avoidr is an interesting comment on the growth of Foursquare culture, but it's not really useful at all.
