I know UVA admins are working hard in order to maintain this site, and of course I do appreciate it. However, I am sorry to say that I believe this site is no longer a forum anymore. There are spammers everywhere around. Download blood diamond for free hd buy viagra at only $5.99 etc etc. These users should get banned and I believe UVA should have some anti-spam policy or sth.
Why don't you consider blocking posting URl or sth? At least banning spammers should help too.
(Sorry I really don't have a clue whether spammers are banned or not, there are so many spammers around in these days...)
