Heyo!
Thanks for letting us know about this.
We've been aware of this issue and this server has been dealt with.
Glad to know that you've deleted everything when this happened.
Suspicious servers advertised by bot is not an ideal server so I suggest to not join them. Also, you can get a new IP by resetting your router. Use a website like https://whatismyipaddress.com/ to check if your IP address has changed.
With that being said, I'll be closing this thread.
