Do scammers know when we're giving out fake information too?

Last Saturday I was on the line with a scammer with an obvious Indian accent (claiming she's from Salt Lake City, Utah... yeah right lol) talking about ''free baby stuff'' for expecting or new parents.

She started asking for my home address, complete name, email, DOB, SSN and lastly my credit card number. Everything I told her about myself, including my ''SSN and card number'' was a total lie. I gave her a SSN of 123000000, an email of Idon'tknow@yahoo. com and everything else false.

All the offers margically went through except for the card section. The lady kept saying her system showed the card is invalid. I played dumbed and gave her another ''card'' with another fake number, false exp date. The lady gave up after the 3rd attempt. LOL

Do they know when we're BSing and giving false information too? Have any of you done that before too? Never say not interested, follow along all the way to the end of the offer but lying to them.
