Not a classic lunatic, but this person seems to be doomposting on linkedin ( sopuli.xyz )
Alt text: two posts from the same person on LinkedIn. First post is someone dressed as spiderman lying on the ground in a park while it rains. Second post is an apparently naked person floating in a water body in a boat with their limbs hanging out.
