You'll be red trusted if you scam any use here or you break forum rules. You can find the rules in Meta.
That's also i think. I didn't sure if this can be a reason to get a red trust but the only thing i know is when you don't follow the rules and you give the wrong information and also if you scam other member here you will get a red trust. So avoid doing that to not have red trust.
no one is getting my question ..I have seen cases where users get red trust because of alt accounts and the accuser show inter account transactions and they say that they are sending each other eth so they are alt accounts. this is not always the case. in my country you can not buy or sell eth on exchanges for $$. i participate in bounties and my friends also participate in bounties they have eth in their mew but they are not sending me to move my tokens just because they think that people get red trust for sending eth to each other because members think that these both accounts belong to the same person..
