I know having 1 mil pure on an account younger than 4 months will get you flagged while Neofriend gifting is one of the safer ways to transfer items. What about Neofriend gifting a few expensive items (PBs, potions, but nothing like stamps) to an account younger than 4 months old? Obviously you avoid the 1 mil pure loophole but your account will be worth above that... is this still suspicious & flag-worthy?
Best case scenario: The Neofriend has been around for a while, logs in pretty regularly, and gifts the new account in short bursts.
Out of all the illegitimate things looked at on the site, gifting PBs and potions is probably one of the least of TNT's concerns.
Worst case scenario: The Neofriend has just logged in after a long time away, transfers en masse millions of NP and/or crazy stuff like an Attack Pea to the new account. That'll definitely be looked at .
