Hmm...
-Smoge16, on bsky, twitter and eka's, writes some great vore and weight gain, and is a dang good artist as well!
-PochaSentai on DA draws really good weight gain (and some inflation too), and deserves more followers, I'd say.
-If you like more comical types of inflation and TF, I'd say PuffyLeizu is a good option.
-BrotherMomentt on DA (also bsky) writes weight gain, inflation, blueberry, and has a cute set of OCs.

Honorable mentions to PinkForsythia, HappyPal, TDookus, Massive Mage, donkdonknever, and Songbird567, but they're a bit more well known I'd say.
I'd recommend more I like, but I think this is a fairly even spread of types of kink, as well as artist/writer.
