A high pr adult site linking to a mainstream site - bad for mainstream site?
 

So lets say im trying to grow a mainstream site to pr6...obviously im not gonna link adult sites or trade with adult sites. But is it bad to have a link from a pr4 or 5 adult site to the mainstream one? Will this fuck things up and prohibit me from getting pr6 in the future?

you better post press releases about your site and hope getting picked up by yahoo news :thumbsup

In theory, links from a lower PR site (adullt or mainstream) can bring your PR down. Of course, I say in theory, because we can't stop people from linking to us if they want to. Also, what would you do if a PR5 links to your PR4 and then some day you end up with a PR6. Would you contact the PR5 and ask them to remove their link?

who knows... but you should test it, and let us know how it goes! :)
