I agree. However, excluding >95% of them (especially including the moderator) while educating the remainder seems sustainable to me (at least on DT1 level) which is what I will be doing.
Ok, you do the stick, I'll do the carrot (if I get back to DT1) by including a couple of folks there that I can reasonably determine to be trustworthy.
I offer free trust-list fixing for exclusion removal; that's somewhat generous as is.
