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.
How about relax the URL policy (in certain cases) for Senior posters with over 5,000 posts or whatever cutoff point that can't be easily achieved, or members for x number of years. That won't let spam in easily.
URL posting could also be restricted to major algo updates.
I wish Matt Cutts would stop by more often, but because of the no links policy, that seems to prevent him from doing so. Which is good. Why? If word got out that WebmasterWorld was a great place to post links to problems about your website, because Matt Cutts visits WebmasterWorld, the forums would be over-run by too many people. I like the no-link policy. Stick with the trusted sites, and whatever is related and approved by the Mods, just as its always been.
