On conservatives@hilariouschaos, they shared a Babylon bee meme saying marines were invading a 3rd world country meaning California I pointed out that Californias existence allows their racist red states to exist. Despite me being “upvoted” with citations that were asked for, and them being negative, my posts were deleted. I wasn’t aware that hilariouschaos was as bad as .ml or worse.
Try messaging the admins about it. If you have things archived, that can help too. If they deem the issue is severe enough they might consider defederation. For now, you can block the instance.
