Actually let me elaborate a little on the reason you see scattered porn on those sites. They are very popular and pretty much they are serving videos all day long. Those videos eat up bandwidth and for a site like this it is no big deal but for a site that deals in videos they have major bills. The fact is, porn pays the bills at those sites, so you kinda have to take the good with the bad if you know what I mean.
I don't think I'm dealing with quite the same pressures though, at the very least its a significantly smaller system. For the time being I'm just going to put together a quick scrubby box though and hope it works good enough to not make my house toxic
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
