There's only a rare case that negative trust user got accepted on campaign maybe less than 10 base on my trust list depth.
I don't know how many negative tagged users have been accepted but I'm sure I have seen users other than OgNasty and Quickseller. I can't remember the name. If you have seen recent signature campaign, you will find out that there's not enough quality participants applying. Last time, I checked blackjack.fun campaign & found they had few open slot but there was not enough quality application. That's what I meant. There are a lot of campaign but lack of quality posters which increased the demand of quality posters; campaign managers are more likely to accept quality poster instead of shit poster. As a result, they would accept negative tagged member depending on the legitimacy of the feedback.
