Another Q : Is it possible that member from DT create his alt to give his feedback into his alt .... ?
Yes it is possible but they will most likely not do it, as it will raise suspicions on their main acc. , and probably cause them to be removed from DT(as in case of QS).
I never have given positive trust to any of my alts (except for testing purposes that were always removed within minutes).
Ok maybe I should rephrase my words better from next time, I meant any type of shady activity( like giving feedback to alts ) will get you removed from DT in the same way you got
Nope, still wrong. BadBear removed me because I lied about being banned. It has nothing to do with escrowing my own deal. Tomatocage removed me from his trust list because of the huge amount of pressure he received from others to remove me.
There are several examples of others who I know have escrowed their own deals in the past, and a few additional people above those people who I suspect escrow their own deals without issue. Some of these people are still on DT, and I have a good reason to believe that their Level1 sponsors are well aware that (at least in some cases) they are escrowing their own deal.
edit: it has been a while since I last tallied who I was certain who was escrowing their own deals, however IIRC I was aware of ~5 well respected/trusted people (myself included) who I knew with certainty that they were escrowing their own deals, and another ~3-4 people who I strongly suspect have at least attempted to escrow their own deal.
