MSMG is a stream where anyone can post literally anything (as long as it's not uncensored porn)
But a lot of users there say a lot of jokes that might be offensive, but as long as you don't do anything to piss them off like make too many memes about being not straight or calling out their homophobia (they won't care and they will harass you, especially if the person you called out was a popular troll like Akifhaziq, Villainous_Blue, or TheHugePig)
But there are really nice people there. I'm a mod in MSMG and I'm bi, I just don't really talk much about being bi. Idk, I just post most of my art in MSMG. It's kind of interesting. If you can handle offensive and homophobic jokes, you can go there. If you can't, it's best for you to just stay far away from the stream as possible.
