Guess what web page from my forum was indexed on Google, for these nasty keywords... That's right, the report an abuse page...
Also, there isn't only one or two disgusting keywords that people are using to find this page from search engines, There are a lot of different keywords...
I don't have any of this content on my forum. The only page that has the word, "porn" is the report an abuse page. ( If you don't believe me, I'll private message you a link )
I'm only going to private message a staff member if they'd like to know the keywords to find the 'report an abuse' page of my forum, on search engines.
So, I'm suggesting that search engine crawlers shouldn't index the 'report an abuse' link.
