It turns out that BadBear does not want me to have separate threads for the three separate issues. Therefore, I have posted below the content of the OPs of the three issues. I hope that people responding can make it clear which of these issues they want to talk about and we'll try to manage this thread as some sort of 3 in 1.
Of course. They control the default trust system, allow it to be abused left and right, protect their clique, and throw everyone else to the fire so they can maintain the image of legitimacy. When I was dealing with VODs abusive ratings I received several threats of a permaban from Badbear claiming I was off topic, some times in my own OPs even. Yet anyone arguing against me off topic was allowed to go on for page after page after page, regardless of it being reported. They protect freedom of speech here, that is until you question them or if it makes their pals look bad. In that case you'd better STFU and fall in line or else suddenly you will find yourself breaking rules you didn't even know existed, and all their lackeys vying for a position in the default trust list will line up to take pot shots at you to earn brown nose points, or to protect their existing privileged position in default trust.
If you ask others to speak on your behalf, then suddenly you are accused of "shilling" or using sock puppets. It is an organically formed coordinated effort to protect their position of control based on self interest. They have a direct monetary incentive to do so, because people seek to trade with those on the default trust more because if they rate you it will raise the trust they have visible by default. If you are new making a complaint, you are just a sock puppet or a scammer and dismissed. If you have a reputation, then they have something to take from you. Either way they still control the situation to their own benefit via selective enforcement of all these unwritten, unofficial rules that change depending on who it is being enforced upon.
There is little concern for the individual here unless it serves some higher use to them. If you are rocking the boat to get some right wronged, you are more likely to get the hammer than help unless it serves them. Your situation with Quickseller appears to me to be a very similar scenario, and no one of much note will speak in your defense for fear of retribution from Quickseller or the staff.
Lets be honest tecshare your comments are always against the trust system so they dont really add much value to any conversation, why make it such a big deal that you got a red trust anyways? You can still use your account as always, you dont seem to have any kind of business anyways here, selling stuff or anything so whats the big deal? You can always take loans or trade if you use escrow
