That sucks, but good on you for looking out for others. What community was it? If you want to call out bad mods, you could make a post on yepowertrippinbastards or fediverselore. Besides letting others know about the injustice, hearing about the drama can be very entertaining.
The “hosting terrorists” part would be referring to the Houthi soldier he interviewed on stream. I personally don’t have a problem with having controversial people on for stuff like interviews but the problem was more that Hasan was trying to make him seem more appealing and only giving him soft-balls.
The “blasting propaganda music” refers to him showing a Yemeni propaganda music video on stream to a guest and viewers. The lyrics were mainly about all the weapons and war supplies they wanted, and what they would use them for. It honestly was just bizarre and left everyone confused since there wasn’t really context for showing it.
Not sure if the “Death to Jews” thing is referring to something specific or just that Hamas is very vocally anti-Israel.
