But that's the problem with the term griefing: everyone uses it differently. I used to be very confused whenever anyone threw around the word griefing, because when I looked it up, it said "playing with the primary intention of upsetting other players" which is not what I have ever done. Then, someone told me it was synonymous with region destruction, the systematic emptying and refounding of a region. To this day, many people still use it in that way. Now, it can mean anything from banning natives and passwording to suppressing posts on the RMB, or even changing the WFE - I have literally talked to people who said that changing the WFE of a region was griefing.
That's what I mean when I say it's a very imprecise term, and I highly recommend substituting descriptions of actual actions for it. For example, it's much better to say "I won't support the banjection of natives or the imposition of a password on Region X," than it is to say "I won't support the griefing of Region X." Literally, when you say the word griefing, no one knows what it means but you - but everyone will think they know what it means.
