Hack Tool detected, 6 minute ban? False ban.

I was in escape mode.. I just joined about 1 minute ago. I kill this BL guy and I get "hack tool detected" I thought it was an error because I didn't hack lol. When I try logging in it says you're blocked from this server for 6 minutes. Why did this happen? I wasn't using any hack tools. Also, my internet is slow. Maybe that's why? False ban. Please help.
