We can't. It's the duty of a mod to close threads who drift too far away and have no point. There's plenty of social threads and possibilities for trivial chat in GDF and OFftopic forum. Plus there're plenty of threads here with quite open topics, so that's just how it is; I don't close more threads than necessary.
I was in a bad mood yesterday so im sorry if i have insulted you mah!
but I agree that shutting a thread down just because you dont agree with the subject doesn't make it right (I use the word you reffering to all moderaters) I was just annoyed because I thought mah was just a forum person but if its the job then there you go lol
