If you did and he had to block them, then yes, there is evidence that both of you perpetuated the encounter. I think that we have a he said/she said situation, except you both admit to either hitting or attempting to hit the other. Personally, I want you both to take a serious warning and a 3 month suspended sentence. Meaning, if any additional issues occur within the next 3 months, whatever ban is given for that infraction will also have a 12-24 hour ban added to it for this one.
Noodles, I don't know that your first teamhit was not intentional. Just your word that it was, and Smithy's word that he was alone and it looked intentional. So we don't have clear evidence that he started it, or you started it. What is clear from your posts is that you both perpetuated it. So I can ban you both for a period of time, probably 12 hours, or you can both take this suspended sentence with a clear warning that it will be tacked on if any other issues occur with the two of you.
