I have the recording, but it is so laggy that it can't prove anything really only that I have a stupid free recording software. I decided to record when a user in the server brought to my attention that this person was hacking, he said "I went in spectator and noticed he was usually flicking his mouse". I was not really so surprised that he was using an aim-guider, so then I got curious and went spectator and recorded it on OBS and reported it.
