Everyone starts at point zero.
Can you determine a person's character by looking at an image? Even if you can, in 1/4 of my transactions, someone other than the person (BF,GF, father. mother, brother, even ex-wife) in image appeared for the meet.
I don't think they are bots. In the depths of the internet, there are OfferUp account holders offering to pay people real money for fake 5 star reviews...anywhere from $5-$30 per review.
If the new/zero accounts were as easy to setup (easy meaning more than 1000 accounts/day), these unscrupulous people would not be offering money for fake reviews.
