By default, all streamers can receive knocks by any other live streamer. This also means that all streamers get a "[username] wants to collaboarate. Click to accept!" notification while live, which is absolutely ridiculous and unnecessary.

Many streamers aren't on Twitter to even know that this feature was forced upon them, until some random person knocks and they're left confused as to what's happening live on stream, ruining their stream experience. They also don't know of the many steps it takes to "disable" it. Due to this, there are malicious streamers that are already taking advantage of this to harass other streamers, specifically men attempting to utilize knocks to harass women, who should definitely be suspended for doing so.

This feature should have been limited to the empty favorites list by default, so that this harassment wouldn't happen, and it would be up to the streamer whether or not to enable this feature, and know exactly which people can knock on their stream.

There's other issues with this feature like forcing someone's webcam to be on, which is extremely concerning for streamers who do not want to use their webcam.

This feature is nice in theory for those who want it, but to force it upon everyone just leads to harassment. Please make it an opt-in feature, go into the database and disable all collaboration permissions from everyone. Let the feature speak for itself by streamers who want to use it. Collaboration is fun, but don't ruin people's streams by forcing these features onto streamers who will never use them, and likely never will when they were harassed because of this decision.
