Doesn't red trust mean symbolize bad image?
if so, do you still believe in projects managed by well-known managers who have red trust?
and frankly like @Wapinter
Depends on the reason why they were tagged in the first place. If the tag is simply not correlated nor related to the project he's handling then there is no reason why not to give a shot. I'm not supporting it but we shouldn't judge them falsely. Although we can't put out that they aren't worth to be trusted, we still can't deny to consider evaluating them first.
