I would like to add, it just feels a bit like they are potentially 'grooming' people to become accustomed to divulging information on the spot.  Perhaps 10 in 1000 people fall prey to a scam after a while of being bombarded with this stuff. Just to get rid of them.  

It might be just my imagination but I get the feeling it means more to them than it appears to mean for many answering what seem hapless questions. To them it may offer a pattern which the criminal underworld ??? :DDD yeah sounds overloaded now... but that they might use in conjunction with putting together formulas for whole new scams. No longer perhaps getting much from bogus cash points etc.  

Just my feeling... doesn't cost anything if I'm wrong.. but I also predicted in 2004 that Tony Blair would be ousted in disgrace, people laughed at me then.  :DDD   Take it or leave it.
