Getting my fair, sweet revenge - very deserved?

If you know or can find out their phone numbers or addresses you can put ad's up on Craigslist.Put ad's with fake pictures saying they are gay and looking for a good time or something like that.It's legal but will cause them a ton of trouble trying to explain that they didn't post the add.They will have a ton of people calling or showing up at their houses.Revenge doesn't always have to be illegal!
