FB Tokens to post user walls - best practices

Hey guys!
Yesterday I lost my app with 6k tokens after 20 min of posting on user walls (i used 2k tokens I think, then my app was blocked). As far as I know, that shouldn't happened, because app should stay alive at least couple of days until users will start to send complaints.

I have another app with 3k tokens but I don't want to loose it, so I'd like to ask you guys how to use token properly withous auto (i think) blocking your app.

Sure follow some basic practice. Only one time my app got blocked because of voilence posted on facebook. Don't post any content with violence in it. That way you will be safe. Just post humor, celebrity etc. It works fine.
Let me know if i can help more
Thanks
