I went through this once. The best way of doing it yourself is to get 30-40 profiles who will report the link as safe. The problem is, it's hard getting 30-40 people to cooperate, as the profiles need to be real, from different IP's/etc. They need to post the blocked link on their wall (it needs to look organic, like a link to a story with a message), get the warning prompt, click the link that says Facebook is wrong (I don't remember exactly what it's called) and send them a message why you think this link shouldn't be banned. In the past, I was able to unlock ViralAccounts with just 15+ submissions, but it got banned again a few months later.
