Younger and more open minded JW's are quicker to skate by the rules on technicalities or loopholes so long as the inactive one plays his cards right and doesn't draw any lines in the sand and forces anyone to "take a stand". I'm sure they rationalize that since the individual isn't physically present, what's the harm? If this was officially brought to anyone's attention, I'm sure it would be stopped.
Inactive brother that on line games with fellow JWs
I play online games and am a member of a few gaming clubs. I'm 38. Anyway, the JW I know that played online games also tended to play the variety of card games like Magic the Gathering and Yugi Man. All of these were around when I was a teenager including online games. None of the JW doing these activities cared if they were playing with inactive JW because they also were playing with "worldly" people too. All of it is condemn and I can still remember a talk in the mid 90's on the dangers of Yugi Man and how it can take you away from the preaching work. Their tune never changes.
