We need a tag for datamined game assets too that don't have a valid source because they were extracted by the uploader.

We could probably go with self-datamine, but then that would probably revive the discussion over datamines in general that haven't been resolved (topic #33230 et al).

mass update user:Blank_User re:stage! non-web_source -> meta:self-datamine

All of the posts under this search were extracted by me, so we can use them to populate the tag if we decide to create it. If anyone has a better idea for a name, you can use this BUR as a template.

I think it would be best to contact users with a lot of game_cg non-web source uploads and have them add the tags themselves. Some users, not just new ones, have sometimes left the source blank or just put the game name, implying they extracted it when they really just got it from some online file repository like mega.nz.
