Yes, Mando I would be interested in knowing who was doing that.
Seriously, I think a 'check six' squelch would be an excellent enhancement to the game! I never realized that even after squelching someone they can still 'check six' you! I have not had that many nuisance 'check six' situations but when they happen you remember them (and the cpid).
Of course, that can add a whole dimension to the game. Hunting down pilots to annoy them could be just the ticket for someones fun! Oh wait, it looks like that is already going on! Fortunately, it is not very widespread. Disabling the 'check-six' feature from someone who is squelched would fix this problem.
