Yeah, seems you are right... Strange nobody noticed :(.
Anyway, the page is down now so it no longer matters :p.
(perhaps a good idea to do a cleanup once in a while)
About ^ and $.. I'm always a bit unsure... coz if a user pastes it like that, eg:
<User> <spreader> go to: http://www.virus.com/infectyou.html
<User> any idea what this is??
then the other user might click on it... and we end up with another infection.
So I can understand both points, neither one is perfect :P.
Anyway, another case: a virus spreading in msg.. then the user might paste it like that in a channel... which we didn't block at all... users are always a fun factor ;).
Basically I always just hope that this stuff is kept to a minimum, since we are presumed to block all the stuff in the first place so it never reaches the user... only thing left is cross-nets (or 'old events' / logs).. like: got a virus on dalnet, then ask on an unrealnet (where you are also connected to) what it is.
