Small fraction of all Newbie and Brand New accounts have links in their accounts , in majority of them , they are with purpose to use power of this forum to increase google positions of other web-pages ,
Regarding the website links in the newbie accounts, I suppose this can easily be solved by adding a
rel="no-follow" attribute in the website URL field. I just checked and currently the link is
do-followed, which is like a magnet for these spammers. If this link was made to be
no-followed, google wouldn't count it as relevant. Hopefully, as a result of this change, the brand new users whose sole purpose is to obtain a backlink to their website will lose interest to join and spam will be reduced, even if it is a small fraction.
