I've read several posts about seo and posting your back links on blogs. My questions are: 1. Do you allow the host site access to your friends list in order to log on with facebook? (In order to reply to a post you have to eaither create an account or log on with FB, hence, access to your friends list) 2. Most sites I've seen don't allow posting URLs, how do you get around that? 3. Most sites require creating an account, do you really have to do that (to create 100's of accounts just to be able to post on each one)? or is there a way around that?
