Note spam

Hi all Isn't there anything we can do about these massive amount of spam on function.mysql-list-tables & function.swfgradient.addentry? I think I speak for us all when I say its getting quite annoying deleting dozens of them each day. And; Is there some unwritten rule how long we keep comments referring to oooold PHP releases (and old linux distros)? (specifically thinking about regarding installation notes). I think I've cleaned those sections up quite well (except from windows notes) but if we don't care about older releases anymore there are few more that can go. -Hannes
