These aren't unnecessary risks though. These are people who are trying to prove themselves. If someone requesting a pardon is serious about getting unbanned then I don't see why they would ruin that chance when they could just ban evade and scam that way?
The reason for voting on a pardon is to see when staff believe a member diverse the opportunity to return the community, it's up to them when they feel a member is able to return, if they deny your pardon, it is because they don't feel like your fit to return to the community, making another gateway doesn't really make sense, that point of DNT having lower pardon time then banned users, essentially the system your request is already in place, just without trading part. You can prove yourself by being active in discord, on the forums etc, many people have done so in the past.
for what it is worth it is nothing personal, the reason you're having such difficulty pardoning is that seer amount of offense for one, and #2 you were cdt member (I think you were cdt leader at the time, correct me if I am wrong), your not going to have easy ride pardoning, as would I if I were banned right now, as I am cdt member, bond holder, and ex-staff member, higher name user tend to have harder time pardoning, I actually say my time would be more difficult then yours, and it should be.
final note if I was still staff I would have voted yes on your pardon as your last offense was 4 years ago, so my reply is nothing person, I am thinking of all DNT's as a whole. not just you, so my second paragraph was to give you a perspective of what I would have thought your pardon.
Actually i suggest a DNT user shouldn't be able to make a suggestion to the forums, not like they contribute.
Don't get DNT'd.
There been a lot of DNT members who contributed highly to the community and in suggestion section in past

Edit: For what it worth conditional pardons uses to be a thing, were users be allowed back with twc (this was before DNT) or with certain thing met, they were removed later on for some reason, I am not sure of exact reason
