While I generally only exclude people cased on the feedback accuracy, I have also placed exclusions for what I consider to be overreactions or a misuse of their perceived power as a DT member, I've done this for non DT as well. That generally applies to a newer member who cultivated enough trust to find their way in. I'll admit I rarely know or care who is actually on DT-1.
For me personally this situation shows poor judgement on their part, but needs to be reviewed based on each case. If they have anything less than this reaction:
I have no problem with my Im an idiot and fckd up banner. Id have accepted much worse. I deserve it, and so does anyone else who had or will be issued one. We all make mistakes in life, its about acknowledging them, getting back up, correcting your mistakes, moving on, and doing better.
I might consider them to have poor character and be weary of including them in my list, as they may require more monitoring than it is worth. I agree that we all make mistakes and in the same way we shouldn't be leaving negative feedback for these users I wouldn't outright exclude them. A lot of these members have redeemed themselves over time and that's the only reason they aren't permabanned. There are other who are still whining about the leniency they've been shown this would be enough for me to remove them from my list but not necessarily exclude them. I see that lack of self awareness as problematic and possibly a reflection of the feedback they may leave.
The thing is given enough time anyone can redeem or disqualify themselves in my eyes, so my list can remain fluid.
