WebmasterWorld has been unique in the way that URLs in posts are dealt with. Unless it's an authoritative well known site, URLs tend to be removed.
I'm sure any member who's been here a while understands the reasons why. examiple: a user drops a link to a competitor and asks "why do they have hidden text" or "look at this link network"... links to malware et al.
What's everyone's opinion? Personally, I'd like to see links in posts relaxed a little, but there still needs to be some kind of ruleset due to the high visibility of these forums.
