This is because the search is down and I became on the idea to gather tags we miss the most. Just make a top 5, that's enough.
Mine:

1. All mind control tags. (mind control, chucklevoodoos, grimdark, crocker corruption)
2. Tags like Makara's, Leijons, Megido's and such
3. Epic
4. Q-dormir.
5. Insecure-illustrator.

I miss all of them tbh. but mostly artists that have deleted their tumblr, so this is the only place you can find their art.
1. Vriscuit
2. Kiwitank
3. BQ/snowman
4. spidermoth
5 gore

What kind of art do they make?

all sorts of stuff. kiwitank had some really nice diverse body types and vriscuit did lots of femslash

Well, q-dormir made cute grubs like these:
