That is mean this persone done something wrong or tried to scam somebody. That's mean do not trust this person.
What should't I do to avoid getting red trust?
I just want to add another issues why other members are getting red trust other than scamming people and spamming around.
We are getting red trust because of shitposting, post bursting and posting a reply without sense or juicy information. Sometime lack of English Literacy can also be the cause for having a red trust.
