Hmmm, I’m hosting my matrix server for years with federation and never had this problem. The only spam I get is via the telegram bridge. Maybe it’s a problem for bigger instances?! On mine are only ppl I have immediate contact with.

Flex luncher is also the best I found so far. Only used it with openbox, so I was lacking the kdeconnect part, which sounds nice. I tried plasma-bigscreen, but that really didn’t agree with me. I’m wondering why there is so little choice in this segment, as it feels like htpcs are a thing much longer than self hosting
