Ban with no reason

I was playing on alserv2019 on Death Toll map 5 and then my screen freezed for some seconds and then it says I got banned from this server.
I checked the sourceBans and it's saying that i have that ban for 30 mins, and banned by console, no reason given.
I want to know if i did something wrong or what happened, maybe I was the wrong person banned. Waiting for answers

Maybe because of this:

2013-08-30 14:01:26 Team Kill I killed teammate Loli-chan♡ with fireaxe. alServ2019 Coop c10m5_houseboat

This is from your event history on HLstatsX: http://85.214.222.39/hlstatsx/hlstats.php?mode=playerhistory&player=9888

The Team Attack Counter is never failing^^

I had the team killing counter 5 of 12 when i was disconnected from the server, and those points were only accidents, 30 min passed and now i'm not banned anymore, thank you for the explication

Read the forum.
The points are something else as real team kills.
Therefore there is a 30 min ban and a 60 min ban

Well its balance by difficult, if you play expert, you get faster a high counter, sometimes i have 1 - 2 shootgun shoots ban me (ok, i stand 1 meter away only and all bullets of the shoot hit) XD so sta away from stupid bots, they got the bad thing, to run and stop directly at front of you

try to help other team mates by cover, heal ect. So your counter goes slowly down.
