AntiFraud rules from a real gift shop for general development

[Man]

Interesting moments that af gets aggro and can be paid attention to.
Points are mostly +3 +5 +8 and the same with negative values. Where there is a particularly large minus, I have indicated in brackets.

Those that increase trust points:

PayPal email the same as user email
User name contains the word "family"
Recipient name contains "family"

gmail or yahoo address used for either
first/last name of gifter includes "and"or"&"

Order is for a product (instead of a gift card so uneven value)
