there's a user (cm0002) who is so fervently anti-communist that they've spent years at this point having a vendetta with lemmy.ml/grad/hexbear.
for the longest time they were taking anything posted to a .ml community vias rss feed and reposting it on .world/or other instances out of spite
they also churn through accounts, so people who block them get to re-block them on every new account they spin up
