seconding discord embeds not being a viable place, but imgur is also bad.
a while ago they nuked a pretty significant amount of their posts, including uploads without user accounts and nsfw uploads, even ones attached to accounts. (though the model they used to do this sucks and had a lot of both false positives and false negatives)
this is funny to say while we're currently disallowing it, and my only preemptive lampshade is "we're working on it", but never trust a platform that doesn't allow NSFW content. they will sell every user out the moment it risks their own platform.
hosting stuff on the internet is a difficult thing right now.
