It is the exposing the information he gave you that caused the damages. In conjunction with your not following through on what you said you would do causes the flag the person could create to be valid.
Perhaps the flag will be valid. However, who is going to support it? In order for the banner and the warning to display for a person, 3 people on their trust list have to support it. I certainly do not see 3 DT1 and DT2 members supporting such a flag. Perhaps the account sellers/farmers can get together and create their own trust network.
