People will never read rules/faq's/tos/ etc if they dont want to. I never read anything when I join up for new things or install software, etc I just usually stick to my 1 main rule which I took to be common sense and that was not to mention piracy topics because it is illegal.
I never even read the rules for here when I joined up (yeah I know I should have) and yet I have still never broken any of them or been warned. I'm afraid the only thing you can do is let the mods do their job and remove any of the threads which get reported - and they are doing this very well -.
As for where the posts might occur I cannot really say because I only live in the newbie forum and answer almost any question I can, and yea there are always some broken rules threads in there but if I spot them, I report them and chefelf, lordvader, heinrich, etc do their jobs and bin them.
I have also joined a forum with the read-only accounts setup and they did kind of work, although not a great fan of the idea myself - cause I already spent 2 weeks reading the forum when I joined.
So for now I say good job to the mods and hope they continue for a long time yet.
