"I wonder what would happen if some rogue elder (on the way out the door) took some S-77 DF forms - filled them out (his get even list) and mailed them in (using the blue envelopes)"
Not much would happen. It would be somewhat a nuisance but not much more.
Watchtower’s service department has over the years gotten a fairly good number of unauthorized S-77 forms, including in the special blue envelopes. Once the local congregation is contacted the thing is realized.
