Maybe criteria would help. Perhaps the ultimate DISer is someone who:
-doesn't take part in or start controversial threads
-gives support where necessary
-offers an opinion when asked without getting preachy
-posts only within guidelines
-doesn't take up too much bandwidth with excessive unnecessary posts
-helps protect other DISers by not asking questions that will obviously expose the real identities of other DISers....
I'm sure there are more.
Nah, I don't fit the description either.
