I find Vod most consistent in his outlook/feedback while red tagging any one.
LoyceV already have a thread to get the user banned for copy pasting.
iasenko is also coming with new ideas .
Look like mdayonliner is now sulken with his initiative (I think after red tag)
coinlocket$ is always busy in busting alt accounts here.

The Pharmacist is a good choice but I personally believe sometime he/she is in a hurry to give tag or already decided on it.

Everybody is volunteering in this forum so picking anyone over the other will be some kind  of injustice to other. Feel free to add others if I forgot to add them.
I did not add Lauda and actmyname as they do not look active here (atleast in Meta)
