The lack of a top-down structure has enabled them to resist infiltration but equally once you add a montetary element, infiltration becomes both very easy and multi-facted. If I was a member of Anon Bulgaria and I needed a monetary gain I would tease the information for a week and then load the links etc onto steemit. And although I'm well aware that this could cause problems and hence might not be the right platform, some kind of blockchain format information bank for the free (yet monetised) spread of information could be an angle that's worth exploring. I certainly hope they've had a change of heart, but I also fear they've been paid. I guess only time will tell.
