I agree that right clicking the name would be very helpful. They could take it a step further and allow a drop down box that has RMT as an option and have their name drop into a different list that doesn't effect your Black list. Grouping these names into a list designated as RMT should help SE to quickly filter through the posts of this list and track common names listed by other players. This could take a snap shot of one line of their post proving to SE that they are spamming a website which is one of many user agreement violations and make it easier to ban them. You have to have an SE account to have a char so it wouldn't take long to ban just those accounts and not have to even investigate reports.
