ArtStation wackiness?

So uh, created artist #508061 just now. Not quite sure how to handle the artstation link because... well https://www.artstation.com/elainetehart goes to a 404 page but https://elainetehart.artstation.com works just fine. username.artstation.com URLs are automatically switched to artstation.com/username on Danbooru's end, so (vague hand gestures)????

I have the same issue with the above user's links but I think that's an exception? These 2 pages works fine for me (sfw).

Yeah this is like... the ONLY artstation account I've encountered like this. It's bonkers.

I think making a wiki entry for the artist with the link would be a decent solution.
