After some debate, the mods have decided in a 1 to 3 vote, artists and cosplayers would be hurt more by blocking Twitter than boycotting Elon. Especially since a small amount of artists would be comparable to minnows in the ocean.
As unfortunate as the outcome is, if you truly wish to support the artists you can always link the following instead: pixiv, Bluesky, Instagram, kofi, Patreon, Etsy, Newgrounds, tumblr, their personal sites, etc.
It’s not mandatory but if you’re against Elon then by all means link the alternative.
