Comment by AlexeyBelov

For the last two years I've been noticing that most comments that are somewhat "strange" are from accounts that are either outright green, or just < 1 yo.

By strange I mean comments I stopped at to check what's going on: mainly uncivil, overly hateful, etc.

There are also users who create multiple accounts that are obviously tied to the same person, after the previous one gets banned. It's an epidemic.
