Three good examples could be DLive, Mixer and Youtube Live. I'm sure there are more, like Caffeine [which has the stupid gimmick of not allowing anything beside their shitty client to stream] or obscure ones like Vaughn.live, but PH is still the best one, imho, the toxicity level is almost always low, and they pretty much allow for any kind of content. I recall someone doing Economy lessons in PH live.What streaming sites could he go to besides Pornhub tho?
going a bit off topic: I wish that PornHub would've bought youtube. I remember being a rumor of ph wanting to buy yt, but it was just a rumor. Too bad, they would've surely fixed jewtube.
(also mixer has some anti-thot rules, which makes it already a god-tier site for me.)
edit: Discord is also launching is "server-wide" streaming thing. Pretty much what TwitchApp\Curse Voice had a long time ago, back when it was usable for voice chat too (they removed it for no fucking reason).
