I get red trust on my account because my sister send merit to my post and I earned other merits from other members too which is what many hero members and full member do too ,many full member send and received merits among some'maybe well knowned friends or something else who knows? You can not track a full member account on merit with out seeing that they sent merit to those they got merit from too ,too many prove ,why giving people red trust because of thise when they are not scammer?
