You misspelled the instance name, but that’s a good thing since pinging the user in question with a mention probably wouldn’t have been a good idea anyway.

The thing that confuses me is that the user has posted a bunch of other content (both posts and comments) such that the ratio of spam to ham is pretty low, and the writing of the comments seems very human (in terms of the inferences it makes and the idioms it uses), so if it’s some kind of repost-bot, it’s a very sophisticated one.

It really seems like a legitimate user whose account is getting hijacked to occasionally post gibberish spam, which is why I find it so weird.
