Oh yeah, that’s one way, though it would still require manual moderation. But I guess if people aren’t abusing the source link, then they wouldn’t abuse the description any more… Another option would be to apply for “joint custody” of an upload, with proof that you are the artist (to the same degree as name changes). Still, the less mod involvement, the better.
 The DNP search feature is even more important than categories, I’ve discovered, since if an artist has changed their name and you search for their old name, you won’t find it, but it will still be blocked. At least a search option would redirect you the newest name and save you wasting 10 minutes of tagging.
And this brings up another suggestion: it would be really nice if comments had a ‘like’ button (hoofbump, if you like), so you can show you’ve read something or to thank someone without needing to reply, along with a notification for the commenter and the option to unsubscribe from a post.
