What's wrong with uaccount?

[starengine]

Someone said to me in a PM to avoid uaccount.
I have uaccount on one account.
It's working OK. No problems at all.

Have others had problems?
Is the recycling of account numbers the problem?
i.e. a bad seller previously used an account number that then gets given to you?

Would like to know.
Thanks.

They lock accounts and its very hard to get the money released sometimes.
