Definitely not Lemmy.ml. I’ve been censored here multiple times. In every case, they just delete the material, and give me no reason, recourse or even acknowledge the censorship. They are as bad as Reddit.
They even demodded me from a lemmy sub I created, because they didn’t like my political bent. At least they did it early, so I wouldn’t waste 15 years commenting and posting, just to see it all deleted later.
I don’t know about the 50’s, but my father and his crew of ex-military hippy activists in the 60’s, used to take pictures of the FBI who were trying to infilitrate the groups as agent provocateurs and/or were photographing the protestors to create dossiers. They then posted those pictures, along with the name of the hotel they were staying at on every lamppost in the downtown area. The FBI tucked tail and left after that. This happened during the Vietnam protests in Missoula, Montana.
Blame the victim. Nice strategy comrade.
