When someone supporting scam activities with their knowledge then it can also be considered under your definition.You can ask the same question to red trust queen and what answer you will get. 
So sportsbet, yobit, and bitcasino participants are supporting scam sites? and how do we treat them? Why aren't they treated like livecoin's participants?
If yobit or other sites were doing the same thing then they also can be considered as trustworthy (IMO).
FYI Hhampuz already tagged the participants for joining on their campaign.
