So, Azulej already answered it:
I didn't kicked him because I wasn't focusing on him

Your ping always spikes from 200 to 800 or even more making you unhittable giving you an unfair adventage over regular players who plays with stable pings, and I only kicked you once in months, so you should be thankfull.
You might not realize about your ping spike during fight. You could use /report to report other players, if the admin ignore report because of personal reasons, you may report them here. This report will be denied for now.
