I have yet to see any of this so called soft core porn. Granted I only watch a few streamers regularly. But I don’t think the problem is as wide spread as it’s been made out to be. I can click on any random twitch channel streaming (and have before more than a few times), and I’ve never seen any of this issue.
Go to the IRL or Hot Tub sections and find something that isn’t softcore porn.
… why is there a Hot Tub section on a gaming site, and what else would it be for?
It’s there to get it away from the other categories. Every category isn’t just a game, there’s other stuff like events, just chatting etc to cover any content that isn’t specific to a single game (like a gaming related podcast for example), so playing a game isn’t required you can just talk at the audience. People who make the sexual content were using those more generic non-gaming categories (as well as popular gaming categories but having the game running in a tiny box in the corner) but advertisers took issue with advertising on the sexual streams, so Twitch made ways to segregate them from the content advertisers wanted to pay for.
