In last two moths I've come across many hackers. One was the same person. They do have crashed servers where I am, but when I'm mc I've been hacked only once.

But once I stopped the attack completely with rc mod only.
It went like this.

I was hosting a roleplay. Then there came this one person, a hacker called Est.
I knew he was a hacker, so I banned him. He still came back, and said something like "'ya thought you were smart, huh?" And I answered "yes indeed." And banned him again and made the room size to 8/8. I bought myself a bit time by annoying the hacker.
Apparently I haven't seen him since.

Lol such a scrub. Real hackers have antikick on at all times
