Recently 3 people left me 3 red tags for absolutely no "good" reason, and nobody said anything, and even if anyone said something, nobody else cared, but if I was a DT member, they wouldn't have dared to tag me.
You're acting a little naive here, aren't you?
You have a negative tag from 6 different members, also, the neutral tag has bad epithets for you, this is not accidental. There is no good reason for negative feedback, they always come because of bad things and reasons.
Think a little better about the second part of your statement, isn't it logical that if you have a proven red tag on your account, you shouldn't be a DT? Although there are exceptions here as well
DT1 and DT2 members who have negative feedback (or are banned)
