A few days ago, a prominent streamer commented on the URL of a clip with an obscene image as a thumbnail on his channel, which caused a large number of obscene thumbnails to appear in the chat window. This was a case in which the streamer was banned by Twitch management while dealing with the BOT.

The streamer is a normal, healthy streamer and has no malicious intent.

The biggest problem is that the management officially counted the streamer for the violation afterwards.
I strongly condemn the management for this.
This is a very childish, poor, and inconsiderate decision that not only discourages healthy streamers, but also greatly damages the credibility of Twitch and the image and credibility of Twitch users.

In order to reduce the number of victims of BOT attacks like this, the ban response should be reviewed, the count should be withdrawn, and a system should be created to respond to BOT attacks.

Here are my suggestions for enhancing security features to deal with this and other BOT attacks.

URL comments should be able to have a configurable confirmation time (preferably more than 1 minute).
URL comment thumbnail display should have an on/off switch.
Even for cell phone verifiers, a function to disallow comments from accounts that have not been created for a certain period of time should be implemented.

A function to prevent users with a high level of distrust, such as users whose total number of comments and total viewing time are below a certain level, from making comments.
A function to identify users who "make the same comments" across other channels as suspicious users with a high probability of being BOTs should be implemented.
The comments of people who do not meet the channel's commenting restrictions should not be disabled all together, but rather there should be a "restricted state" where only the distributor and moderator can see the comments.

Attacks by BOTs are becoming more vicious every day.
It is your responsibility to protect healthy creators from them.
Banning creators and being "quiet" about it is not only a dereliction of duty, it is the worst thing you can do to make BOT vandalism redundant.
