Right, I agree.
But the video would be self-verified with the phone number on the paper and unusable by fakers to enable them to run their bait and switch operations.
True but I think you will find most of the fakers don't go to the extent of verified ads and if they do its for bait and switch which will still happen with the verified pics and video with sign and number. Very little you can do to protect yourself from B&S if from same group other than walking when you realize it happening.
We had someone walk on Eve the other day because she has changed her hair colour from the ones in the ad and haven't taken new pics. Difficult because she has changed colour about 4 times in last two months and cut it twice so hard to keep up. It was obviously her, same body but when they saw the hair they walked, their choice and their loss. Still shaking my head on that one. Have have no one with that same body and appearance of under 20 yrs old. (she is 21 fyi)
