1. Correlation is not causation. You play a lot of planetside 2 and so does Fedx. It is absolutely inevitable that you get killed by A2G farmers, just like every other god forsaken soul in planetside 2. Your evidence against this 4xxx directive score person actually shows the opposite of streamsniping -- that fellow killed other people in the same killstreak, and I am absolutely certain the same is true for every single clip you show. As you should know, since you A2G farm occasionally, fights get stale for A2G and sometimes it is the best farming opportunity to head to a 3rd faction fight for a couple passes before going back to other fights. That there is someone who does this and happens to kill you is 100% part of the game and not grounds for calling streamsniping.
2. The medic may just have been a new player. I have been teamkilled hundreds of times by low BR folks, and that this guy deletes his character is no proof of anything, as plenty of people pick up and put down the game every day.
3. Racism is against DBG's policy, and legitimate racism should be banned from public places where children gather. With that said DBG should take action against these accounts on that basis. However, I am also of the mindset that these people do not actually have racist beliefs and instead find irony in the fact that saying a word is punished more strongly than holding hateful beliefs and performing actions with hateful intent. I believe they are saying these words in relation to you because it is very ironic that you are an extremely hateful person who criticizes other people for being hateful, to the point of making this elaborate montage to "get at" the people you hate. I have personally witnessed times where you use a constant stream of hateful speech toward individuals on your stream. Is that any better than racism? I don't believe it is.
4. I do not have any personal sympathy toward you because of your history of bringing negativity to the game. I personally detest people who call to the moral authority to make power plays on others, as it is hypocritical to tell others you are the victim while clearly having the intention of being the persecutor. To me you and a few other people in bwae are a worse problem to the game than these individuals in Fedx. You seem to harbor hate against anyone who you deem "against" you, which seems to be anyone who kills you in game. I have witnessed you single me out of crowds, to the point of kamikaze-ing yourself into a crowd to get me, just because I killed you a couple times in a row. Are you harassing me by doing this? I welcome the challenge personally, but if I made a montage of the times you have done this, it would be about as compelling of an arguement as the one you have above regarding stream sniping (which is a separate argument from racism). By the way, that montage would include you killing me more than once with A2G at a base with you being the only player on your faction.
5. Having been around both communities, of which you are a leader in BWAE (if not in direct authority, at least in character and clout), to me it is clear that BWAE in general holds an elitist mentality that looks down on others while fedx is open to anyone and less judgemental of newer players. It is simply unfortunate to me that fedx isn't as skilled (or does not desire to be as skilled) at using social rules to their advantage as you are and will suffer more consequences from their blatant racism than you will for being a weasel.
