For me, there's no such thing as getting unfairly frozen. Sometimes TNT just takes time to act... I've seen a lot of people saying things like "I just got frozen and idk why, I always follow the rules... The only thing I ever did was buy an UC but that was 5 months ago ughhhhh" and I'm like... really?
I think it might be related to the anger of getting frozen and the nature of human beings of not accepting their own mistakes, so is way easier to say TNT does a shitty work than actually stopping and think what you did that could have triggered getting your account frozen
Of course TNT does screw up a lot, but honestly most people who say they got unfairly frozen, didn't.
