There should be a voting system where forum members can vote out any DTs they feel are not supporting the forum and use DTs' power to bully others in the form of threats.
There is no point in voting in this case.
DT lists are a matter of personal belief of each member, so for example, if you or Don Pedro Dinero (or anyone else) will edit my DT list (voting or in any way), then I going to exclude myself from the DT system.
If you think that someone does not deserve a place in DT, then state the reasons for your claim and address the members with whom Don Pedro Dinero's judgment is Trusted.
He created a thread about giving some people a neutral tag but if you check his trust page, he gave nobody any trust related to it. This means he used that thread to ask if it is worth it or not. But a good DT should know that is not how DT works.
He really needs to read more about what DT is used for.
Opening that thread, where he asks others' opinions if a situation is worth giving a neutral tag, is probably a good step for learning the basic principles of the DT system. Instead of leaving the neutral (or even negative) tag first, he decided to ask the other members for their opinions.
I always support, if someone doesn't know something, better ask.
