Why not implement Two-factor authentication, this will speed up all the manual work for all those suspicious accounts.
If you implement this i'm sure there will be more customers flocking in, because i have more trust in you than Bter/Vircurex.
I fully understand how your current system can prevent frauds. That's why i always have my nxt in your exchange.
But with help of Two-factor you can still use your current security system on top of it.
eg. Dectected suspicious activity relating account ownership->ASK TWO FACTOR->Approved/Not Approved.
Detected suspicious activity relating to fraudulant funds->Suspension until manual investigation.
Two-factor authentication is:
Fast.
No more suspended account with this.
No need to prove account ownership in order to withdraw some nxt to a friend's account, or a new account.
No more desperately withdrawing some nxt because you really needed at the time just to be delayed in the suspicion list.
If such system is too expensive, i'm sure you can have a kick starter donation nxt style until goals reached then we have it implemented.
This way at least, we know when it will happen in the future.
Or is this too complicated? I'm no coder.
