They're charging on windows like hordes of zombies attracted to smell of flesh leaking from a bus as it inches forward. It's a horrible sight.
They're all paid accounts mostly claiming to be from poorer ex-Commonwelath colonies and some deep South Asia, slowly spreading eastward. Many are obviously pasting LLM generated responses, sometimes even leaving in "here are response ideas for such tweet" parts. They're slowly giving up on trying to say anything relevant to Twitter trends and resorting to cultist Islamic or biblical something, but they're still operating in some crazy numbers. Blocking or reporting makes no difference since they never get banned anyway and the accounts are constantly rotated. You can't block 10m acccounts manually.
It just makes no sense that this is even a naturally occurring problem that can be mitigated by some tips and tricks. Clearly it's organized, connected, with a lot of money and effort poured in.
