False STG validation

I still, to this day, have no idea how they confirmed me as being a part of an STG [Security Threat Group]. I’ve been in one fight that I got wrote up for and never had a weapon on me at any time. They don’t have any kites with my name in them and they won’t tell me anything. One day they just said you confirmed a member of an STG and locked me up.

I’m not a part of this group they confirmed me as, and the only way out is to take a G.R.A.D. program, and to do this I have to sign a paper saying yes I am a member, when I’m not. Doing this will put my life in danger as having marked an X to something I never was a part of.

They should change some rules in TDCJs in Texas because these GIs are just confirming people left and right saying they’re confirmed when they are not. I’m not the only one who’s been done like this.

How can I make them tell me what evidence they’re using to confirm me? What could I do to help people like me get out of AdSeg without taking that G.R.A.D. program?
