lol, = “___”, “x” whatever.
I guess a lot depends on the account.
For one-visit SPAM accounts it matters less if someone saw “Suspended, SPAM”.
But IMHO for established members that had a rare mess-up or went over to the dark side it would be more respectful and more tactful to give a more “generic” non-specific reason like “non-member” or “inactive”
i.e. enough so other members will know they shouldn’t expect that member to respond to mentions or messages - without putting the bad member’s head on a pike.
