Username change logs can be a privacy invasion, as pointed out below.
If instead you want to track and ban changes, you can think of 'ban suspension'.
"Ban suspension" means that if a suspended user changes their username to avoid punishment, Twitch will automatically ban that user from the channel.
Through this, it is possible to operate a warning system beyond the rigid punishment system of bans.
It may be awkward because it is a sentence through translation, so I ask for your understanding.
