Unban from Rust experimental server

How do i unban myself from a rust experimental server? i can join other servers
i play on cracked rust experimental

I changed my steam account then proceeded to delete my rust folder and put the folders back again as if it was new..Still banned..
Changed my IP, My brother could join, I couldnt.

How?
Thanks

reinstall windows - it will change ur ID

It didnt work. Things ive tried:

- Re-installed Windows. [Youtube video guide i used: ]
- Changed my IP
- Reinstalled windows so basically changed my user account
- Changed my name



What else is there to do??
