User blog comment:Sannse/How to Get Unblocked/@comment-5076341-20140914062934/@comment-452-20140914135757

For the record, The Great Lord David, that comment was meant to be an example of something that Wikia Staff permit, but is unfair, not an example of something you should do.

I think SemanticDrifter may have already written a blog on that topic.

edit: He didn't specifically address "What do you do if you get blocked for doing it, or threatened with a block", but he did mention using Special:Contact "If the friendly approach fails", so that's covered.
