Brazil. Last year I effectively blocked Brazil for a while. Ultimately I settled on three possibilities for the traffic I was seeing:
01: DDOS
10: Residential proxies
11: Somebody DDOSing residential proxies

I suspect these TVs either come with residential proxies set up from the factory, or they have such poor security that they’re instantly hacked. Either way, TV manufacturers (including reputable ones like LG) are to blame.
I don't think residential proxying is all that shady since groups like Cloudflare have made it a necessity. However, having it out-of-the-box on a name-brand device is extremely shady.
