You have a well deserved list of rules which should be followed before tagging any person with red here.
But I found one of the rule pretty annoying and not Justified in any way.
Harassing a DT *Subjective (Extreme harassment)
This is totally Irrelative point for being tagged and can directly pointed as an abuse of power. As if a person tries to complaint against any DT or its action it would be considered as an harassment which looks totally wrong.
I would rather suggest you to upgrade it to
Harassment by DT which would better support the people and give them a chance of protesting against abuse.
There is a difference between a person challenging a decision and (e.g.) someone calling Vod a pedophile and making fake reviews about him on external websites.
That sort of behaviour is extreme harassment. (and in my opinion deserves a red tag)
My intent is to take the list and turn it into a poll later for community voting on any subjective topics. This will provide good data of what other people expect to result in tagging.
Having a bit of a charter of conduct will also make it easier to discuss controversial tags.
