Restricting streamers from discussing mental health.
I occasionally see streamers who promote therapy or claim to have mental health issues, when they really are not qualified to be involving themselves in such matters. Even worse are the situations where it's clear (or it cannot really be verified) that a streamer is claiming to have a problem, just so they can solicit for subs/donations/boost their social media presence.
I think the topic of mental health is just too personal and risky for someone with no background in treating mental illness (or appears to be pan-handling) to be discussing on their channel. I think beyond telling a viewer they may want to look into seeking professional help (if there is a situation where this is necessary), there needs to be more restriction on what topics a streamer can discuss/personal information they can disclose.
