After reading the entire PM conversation, I would agree that Vod was abusing his position on DT in order to entice you to remove the rating that you had at the time against him. The question of if this rises to extortion or not, I am not sure, however unfortunately when you are in power around here,
not very much will happen to you after you extort someone.
I can't support the activity that was the root cause of this dispute, and others in the past have received multiple negative ratings for similar activity. On the other hand, I don't support the public lynching of members after making a single mistake, especially after they have made the relevant parties whole (it is my understanding this has not happened in your case).
I believe Vod's claim that you are lying stems from what was likely you misspeaking a single time, and probably does not fall into the category of being dishonest. Based upon the fact that Vod was previously asking for you to remove your negative with the threat of leaving a negative rating himself, I would question the legitimacy of the claim that Vod "distrusts" you, although I disagree with this standard to leave a negative rating.
I would suggest you contact dooglus, Cryus and HostFat about your concerns, and ideally they will remove Vod from their trust lists.
