Reference post: Why have I excluded members on my trust list?
Since I can't give an explanation or Reference link with my trust list, I'll keep track here.

Currently excluded
~cryptohunter
Bad judgement, conspiracy nut, and spamming many topics with his "ideas".

~BiPolarBob
Hacked account.

~Gleb Gamow
Several reasons, see his red trust.

~gamerfan
Red trusted user who was included on DT.

~Alex_Sr
Right after being on DT2, he left positive trust to the many users he seems to like, and deleted it after being excluded. Apparently being on DT is more important than leaving accurate ratings. He is "still very inexperienced in matters of trust".
Reminder for myself: review this one somewhere in the future (weeks/months)

~SmartPayMINT
Red trusted user who leaves retaliatory feedback and was included on DT2.

~LoyceValenzuela
Imposter.

~IdiotCoder
Leaves ratings without reference, and left red trust based on a user's religion (reference).

~BetKing.io
Scammed me out of $700 and left 6 users fake retaliation feedback after I opened a scam accusation.

~griffoninvest
Leaves fake red trust to spam hunters after theymos wiped all yobit signatures.

~BillyBurns
Shills hard for a scammer, and leaves fake red trust to people who tagged said scammer.

~Kriptonian1661
Leaves fake red trust.

~Blazr
This user's feedback is for sale, the account might be compromised.

~Vadi2323
This guy gave yahoo62278 red feedback because of his personal vendetta against another user. See Reference post.

~wolwoo
1. In one week, this DT1-member added 24 users to his Trust list. Most of those users never left any feedback and don't have a custom Trust list. Therefore, they don't belong on DT2, and the user who adds them doesn't belong on DT1.
2. 4 months ago, this user left positive feedback to 16 users, all without reference link. The only thing they seem to have in common is their nationality, just like the users on his Trust list. That shouldn't be a reason to give them positive feedback and/or DT2-powers.
3. This user leaves retaliation feedback.

No longer excluded
~peloso
A red trusted Merit abuser who's trying a hostile takeover of DT to clear his red trust.
Update December 4, 2019: peloso asked me to reconsider, and I'm giving him the benefit of the doubt. He still has 6 more exclusions to clear before reaching DT.

Currently not excluded because they're not a threat to the system, but I'll exclude them if someone ever includes them again
~mike
A Brand new user who somehow was included in DT.

~game-protect
Loads of red trust.

~BITMIXCOIN.IO
Scammer called out by me.

~John547s3
Scammer called out by me.

~ChangeNOW
Scammer with red trust from me.

~bountyhunters.io
Potential (failed/prevented) exit scam.

No spam
All my threads are now self-moderated to stop signature spam. I will remove all irrelevant posts. If you quote the entire OP, your entry will be deleted.
Once in a while I'll summarize posts and clean up this thread.

Share yours
I encourage everyone to keep track of the reasons behind their own exclusions too.
I don't think it's helpful to create many topics on this, feel free to use 1 post here for yours (including reasons), and I'll link it from the next post.

Static list?
This list isn't static, I'll add, change or remove entries when I think it's needed.

I've always tried to be very conservative when leaving feedback and when including/excluding users from my Trust list.
Today, I made my first DT1-exclusion:

For the above reason, I ask all other users to consider excluding ~wolwoo too.

As a reference: this is what I consider correct use of the Trust system: LoyceV's Beginners guide to correct use of the Trust system.
