80% disagree. I think it should maybe be at the admins discretion. Some of us have multiple professional roles, so having a sig that says irish webmaster & SEO Expert has a more negative expected value to me than having 2 seperate links.
Also, I don't like when spammers end up affecting my sig length - common sense can do that I think...(sometimes)
We are (mostly all) webmasters and surely on a webmaster forum we all deserve the right to pimp /showcase/disseminate our latest wonderful sites in our sigs, since it is us that keeps this forum in business in essence. No? None of us are selling crack or anything else unsavory from our sigs are we?
Good moderation keeps spammers at bay. Common sense should do the rest in most cases.
my 2p's worth - interested to see what others say.
edit: I am guessing my sig is the longest ?
