If we restrict newbies and jr. members to wear signatures, the forum will lose a lot of traffic, which could downgrade it's rank e.g. in a google search, so there's no 100% good solution, unfortunately...
Hi mate, I dont know on what forum you have been recently but newbies and jr members signatures have been disabled since january and the forum hasnt lost a lot of traffic. They can buy a copper membership but most of them dont do.
I have to say though, that Ive always defended that too drastic measures would affect the traffic, this is not a matter of opinion but of empirical evidence.
We are talking about going further, maybe disabling signatures until full member would be a big step but if they were disabled until member status Im sure a lot of traffic wouldnt be lost.
