Sure it's not that sex appeal focused streamers are never in the game categories but it is much rarer than it used to be. The IRL category has helped by moving the majority of all these streamers to one place where you can go watch them if that's your thing. All that is needed is for Twitch mods to be a bit more active in retagging such streams to IRL instead of the game category. In general I think that they are doing a great job. You used to see a lot more League of Legends streams where a female host dressed in a revealing outfit had her cam much larger than the gameplay and it was clearly more focused on sex appeal than gameplay, but that type of stream is now mostly cordoned off in IRL. A simple rule like "streamer camera can only take up X% of the screen, and gameplay must take up at least Y% of the screen" otherwise it gets retagged as an IRL stream solves the issue.
