the tidal wave of spam? interesting.

i am member of a group, public, 876 users as of right now, another openstreetmap india group and that one has 1350.

only the osm-in has some sort of "spam" where i see occasional crap thrown on but that gets flagged and removed quickly.

i don't know about telegram but my matrix account(s) are pretty public but i have basically never gotten a stray spam. as i said, one group has a "couple of spam messages occasionally" but i can "report" the user and check tickbox

"Ignore user Check if you want to hide all current and future messages from this user." which should be good.
