I do agree that an instant perma ban is a bit unfair, I will go ahead and unban you. However, RDMing 2 people for following me can be dealt with via other ways besides flat out RDMing. If they are on your property you can warn them to get off of it or else they will be shot. Or you can call the cops and file a report.
However, I still do not know who banned you and would like to know, as that will be important information for the logs.
