Seems like another of those bots posting copypasted text from reddit. I deleted the spambot useraccount.
We have a hidden system monitoring all new users, comparing them against a vast database of known spambots. And then another layer, visible to the user, is hCaptcha. Unfortunately, it seems like every now and then a spambot manages to get through the defences. At the moment I can't think of any further means without making it too clumsy for real users, so we just need keep our eyes open for bot accounts.
(I'll leave this topic here, usually I delete both the user account and all the posts made by that account. But since we have this bot-related discussion here, I let it be.)
