I work for YouTube and I did not know this was possible -_-; Or maybe I knew and forgot.

Just reintroduce the feature a few years later when everyone forgets. You’ll get a promotion from what I hear.

I had no idea about this too. I think it makes sense then that this is being removed. The feature is not well known but it must be putting a lot of burden on their team to keep it clean and protect it from abuse.

Exactly, I wonder how many people even know of this. From what I've seen following a few youtubers, most of them request that you contact them through Twitter or Instragram DMs.

I've used it ages ago. Some youtubers read them and made response videos out of them (Q/A).

But later some of them disable it as the only got a flood of messages through it.

I just noticed it being used by a few channels in last few months... and it's gone.

It might've been used more during live feeds?
