Need to get the IP of a disruptive user

An ex moderator on my instance has recently been kicked out and has been going out of his own way to cause trouble. Generally, this has just been spam, but recently he has been attempting (and failing) to run scripts.

I would like to know if it is possibly, either through Peertube its self, or by looking for a specific entry in the access logs, to discover the IP of this particular user so that it can be blocked.

In administration → System → Standart logs → Info
maybe you see him?
