That is equal parts ridiculous and terrifying.
Google stepping in on chats to moderate them automatically without anyone involved wanting them to do so is awful. Issuing entire account bans for benign posts is absurd.
If they don't want people spamming chat with emotes, limit the number that can be posted. Add rate limits if the problem is too many messages in a certain period of time.
It's a totally backwards approach to take, and the worst outcome should be a temporary suspension from YouTube chats, not disabling the entire Google account.
For many people a Google Account is so important that you have to wonder if Google should actually have the ability to issue permanent bans for just about any reason other than something like a court order.
I rarely ever view YouTube live streams, don't participate in chat, or leave comments, but it makes me very glad that I use separate Google accounts for each of their services.
Imagine once people have libraries in Stadia tied to their Google accounts lol.
That's absolutely minor compared to the impact of being locked out of your Google Account.
Many people use that as their primary email account for
everything. I can't even imagine what it would be like to try and recover from that or migrate accounts to another email address while being locked out of it.
Google's recovery process for Gmail accounts is bad enough as it is, as I had to help someone with that a few years back. They had to enter the date of the very first email they received. Who knows what that is? And even if you still have access to the account on a signed-in device, that's no help if the email was deleted rather than archived.
