@SumOne, the post you quoted was highly likely to be from an account made for spamming or scamming.
Inane, LLM-written content in necro-threads is one of the methods for making accounts "clean" before the spamming/scamming starts - - either immediately or after some months of hiatus - - the hiatus too adding to the "cleanness".
Another forum was virtually "taken over" by these bots/people, so I think it's best to be vigilant about these (but do not know at all whether it helps).
BTW, I reported that post, and now see that that account's posts have been deleted.
Thanks, mods!
best,
bert
