Is the technical information in the email common knowledge there? If this information is known to only a select few this thread could help them close in on him.
That could be true, but the person concerned no longer lives in this country. He is basically retired and now lives abroad.
Also it was maybe up to 2-3 years ago he worked at Bethel on the computers.
All I can say if the WT is that paranoid about "apostates" etc that they have to go to such lengths. Then there is something seriously wrong with them.
