Ok all tag links must now be verified by a moderator before being displayed on the site. The moderation rules will now be a bit stricter, any links should provide context for the purpose of that address which would be useful to other users e.g. "Wikipedia Donation Address" linking to wikipedia.org = good, "This Address Scammed Me!" linking to reddit = bad.

You can now also submit tags verified with a signed message, rather than a link, which will be approved immediately. Blockchain wallet users can do this through the wallet ui label address function.

I will add a way to remove tags soon.
