Re: Scammers and time wasters do blacklist people...
I once fell foul of the 'bait & switch' whereby a very attractive lady asks if you have a moment & then introduces her colleague (usually male) to ask about religion...
My question of "How do I know you are the right one?" caused concern, especially when I pointed out that statistically they were worshipping incorrectly due to the plethora of beliefs & most (if not all) belief systems state that people not of that system are not going to heaven. Apostasy was ruled out as that's also a no-no, so no hedging your bets.
All in all, a fun discussion... I enjoyed it anyway.
