How any missing artist tags do I need to track down to get the badge for it?
I already got 1
Generally if I see that someone has submitted 500 or more valid artist aliases I give them the badge. Some others have also gotten it by helping with some really big bulk work, like during the Tumblr diaspora, or finding something so horribly broken in the artist aliasing that it takes a week or more to get it straightened out … which thankfully happens less often now that we’re on Philomena.
I haven’t been able to work the aliasing thread for awhile because of IRL stuff, but I am looking forward to being able to get back to it in April, so I’ll keep an eye out for your alias submissions :)
