Regarding number 1, no you didn’t break that rule with advertising. Note the use of the word “primarily”. The type of site the rule is meant for is a site that just about anything you click on is going to redirect. When that rule was written, there were thousands and thousands of adult sites that existed primarily to make the user end up on a different adult site.
Number 2 is about reselling dreamhost services, or giving them away. In other words, you could not give your friend free hosting space to run their own forum, but if you want to run two different forums yourself that is fine.
