Well I guess I better defend myself by telling my side of the story.
I was outside ile a veche capturing trader ships, my first battle was against a trader brig, pickle, and brig. I joined in as did blindshot and 1 other person. That was fine, in the end I needed the help of the other guy to deal with the brig and not let the trader ship get away. Blindshot as far as I could tell did not assist in the sinking of the ships. What he did do is when I was boarding the trader ship about to take it, intentionally rammed me away from the ship and gave me boarding interrupted. He then immediately boarded it himself and took the prize.
I didn't do anything about it beside say that it was a dick move.
So when I started my next battle against a trader brig, start killing it, then with 30 seconds left on the timer blindshot joins again. Being annoyed the told him not to pursue. When he did I fired a few shots at his sails to try to deter him. When he finally did not I demasted him. I then took my prize.
If it wasn't for the previous battle I would have left him be, even if that meant I lost the prize. But because the previous battle, he atleast looked like he knew exactly what he was doing by interrupting by boarding. I wasn't going to let him do it again, as I put forth all the work and get no reward.
Unfortunately I have no proof for my case as I was not aware I would be on trail for it.
That's how it happened from my point of view. If action needs to be taken as a result so be it, I acted as I saw fit.
If blindshot really did not have the intentions to intentionally mess with me than I apologise.
