They will allow it. And y'know, it is how it is. Big companies can't make online streaming as focused as it used to be, so you gotta just leave the door open for almost anything.
Nobody wants a sort of strict "Twitch Law" written into the TOS. Everybody wants ban appeals to be taken seriously and most of the time people don't want permanent bans to streamers. However, as everyone also knows at this point: Twitch staff has a type of content creator that they treat favorably. Like, intercourse on stream... But frankly Twitch and the rest of social media space has become less and less "pure" in the past few years. OF thots use all possible outlets for self-marketing, because why not? The market for that is still ripe.
i think if Twitch is going to allow it, then they are going to have a problem with these people making most of their money on OF, or otherwise off-site revenues.
one way I think they could go about it is allow streams of that content have a Paid-sub stream only. Where you cannot even view it unless you are a paid sub, or even a scertain tier-level of paid sub.
I said this before in another thotty thread. If they wanted to age restrict these adult streamers then fine, and the best way to do that it by forcing a paid account verification (something small like one dollar or whatever). OR the better idea is what I said above. When a streamer is doing an AO showcase then they must set the stream to subbs only which means everyone MUST have paid to even see the stream. And even better the streamer can force it further by saying only Tier 3 subs can see the stream (which is a lot like members only videos on youtube). This makes sure that the people viewing are at LEAST old enough to have their own bank card. It wouldn't eliminate it completely but it would help.
However I think a lot of these streamers are getting donations in cheers and subs from 12-15 year olds, and therefore may not want to limit their content in that way and OF doesn't check age whatsoever which is weird. OF also has a good revenue split so of course you want people to go pay for your photos there.
Bottom line I think Twitch is upset that the revenue for the streamers using their service is being pulled from offsite which means they aren't getting a cut and therefore are going to inflict this harsher 50/50 split onto the top earners to pull more income out of it. The question is how will the big streamers respond to it? My guess is that they'll be more upfront about pushing people into other forms of donation like paypal tips, patreon, etc and further cut Twitch out of the deal.
