Topic: URL links do not have rel="nofollow"
When inspecting html from forum posts I noticed links do not have rel="nofollow" attribute in them. This leads to more spamming on any punbb forums as it increases the target websites seo rankings.
Is there anyway to incorporate such an attribute to posted links?
Edit: I also believe a large number of outgoing links from a website reduces its seo rankings as well as the score given to each of these outgoing links in Google page rank.
p.s. it is not possible to moderate all links so a link to a porn site on the forum could damage the ranking of a website. I believe this is quite important. (To the extent that if this can not be fixed I will host my forum on a separate domain to my actual website)
