From an unbiased standpoint, I can say that him doing this wouldn't surprise me. If you look at OP's snapshot, the round had just begun, so it's nearly impossible it was a mistake of sorts. Think about it; there's no enemies around, it'd take multiple hits to kill OP, and Skrubbin has played long enough to not make this kind of mistake.
Hope justice is delivered.

"the round had just begun"
Incorrect, the rounds do not last a mere two minutes. It's not even clear whether or not he had just joined the server, let alone had just spawned. The screenshot shows someone being teamkilled in spawn, that's it. No, that does not mean I am condoning teamkilling, it simply means that without knowing all of the facts, it would be wrong to issue a ban.
What was the exact date of this incident and, if possible an approximation of the time of the occurrence so that this can be looked into.
