i don't know about the nonhumans thing, more of them sounds fun in concept but some people don't know how to play it off without overusing the novelty. for example, in one game i was in, let's say this character was an electric specter (for the sake of anonymity) that corrupted video feeds whenever they tried to use the camera, but audio and text worked fine. this person always had their character respond in video no matter the post content whether it was a slice of life prompt or distress beacon solely to go [tee hee the video is all static!] instead of going audio or text. it didn't seem IC either, because the character wasn't forgetful or a troll.

it can get tiring quickly.
