There's a ton, and I'm not surprised in the slightest. Just having a boob window on the side of a Twitch stream guarantees easy hundreds to thousands of live viewers within a month. The girls don't have to "whore themselves out", and get much more money for it. You could have a personality of a dead fish and hundreds of people would still watch you, because the Twitch simps can't admit they're coomers and would rather watch literally softcore on Twitch instead of pressing ctrl+shift+n and going on Pornhub.
See Pokimane, she's just a basic whore that doesn't want to admit it despite her many obvious "PR slips" that Twitch doesn't give a shit about because double standards and muh feminism.
