Thanks for the feedback bigredseo.
Being do-follow is intentional. Spammers fluff will be removed whether it is dofollow or not. If they want to create quality guides, etc. and have linkback in their signature, then that is fair. Like it is at other popular forums. Hopefully, in time, there will be enough awesome moderators who can help with issues like that.
I know HD is "rel=nofollow", but I still post here. If it were dofollow, then that would be a bonus, and no doubt might increase the chance or more experts contributing quality content, but that's up to the owner of this forum. I'd rather just leave it as dofollow.
