I'm a little worried that my adsense account may get banned due to user submitted forum content. On one of the forums I manage the content is starting to get a little profain from user submitted info and I was just curious how strict google is on this. Should I go in and setup blocks for particular words just to be safe?
You absolutely should. And Just for a precaution just block the ads for couple of days. Just check( if possible) all the postings and do some filtering. Forums stands a high risk at getting banned by google due to excessive member clicking, advertisement and signature links to unaccepted affiliates and contents like gambling. So be at safer side. Once an account is banned, it is banned!
