Is he alright? Is something happening? If it's all ok, are there any other artists that use extreme amounts of saliva, like him?

All they did was request a takedown on all their art, which was handled yesterday.

Are there other artists with his style?

He's still on FurAffinity, you can find his stuff there.
Remember, you cannot rely on e621 all the time, we have a DNP list that changes all the time.

Anyone have an idea about why?

If you're interested, they made the following remarks in a Twitter thread :

A bunch of people have asked me about my art being taken off e621. I had it taken down as an impulse decision. I wanted more control over where my artwork is posted, also wasn't feeling great about some older work i don't like anymore. Now i regret doing it like i did (cont.)

Wasn't feeling great mentally in general when i made the decision, if you followed me for a long time you might remember i vanished and deleted artwork in bulk before. Not getting into details, i'm much better about this nowadays but i still have these moments.

I recognize a lot of people liked that gallery and met my work through there, i'm sorry 'bout this. I'll try my best to dig up a lot of my older work.

Well, I hope they know that they can have their artwork undeleted here...
