"It can be viewed as a problem account at the same time as trading items of low prices and uncertain users.
1 old player need over 10 accounts (but only 1 real user) to keep fusers and billions of gold.
Fuser trade to 0 gold ("untrustworthy price") = may have cash transaction --> temporarily suspended
An old account trade gold to a newly registered ("uncertain") account = may have cash transaction --> temporarily suspended
Individual transaction = risk your account.

This is bad news to old players who do frequent individual transactions.
