Changed artist name from 'wasd' to 'wasd_(yyo694065745)', because there is another artist who's name is 'wasd'.

Mm, another? There are probably lots of artists named 'wasd', typically whoever is the most well-recognized artist gets the unqualified name though (unless the name is so ubiquitous that it has to be a disambiguation instead).

Pixiv only pulls up 4 wasd's on a partial match search for users (with one being a blatant plagiarizer), and the other is already known here as wasd_(mild1020). I don't see too much of a problem with using just wasd.
