It's absurd, yes, but unfortunately, for these things you can't simply block or delete those accounts because they would just end up coming back with new ones.
Aggggghhhh... If only there was a mechanism or function to make those SPAM accounts invisible to the public (Front-end) without having to block or mute them manually. Just by giving them a massive automatic downvote, like a blacklist or something like that... 🤔 Wait... Of course such a thing exists! The Reputation!
But it seems some people don't even consider this important. Even I wouldn't know how this could be useful to us. 🤔
