If by exemple a user get locked for scamming xxx f, then repay and get unlocked. And he get locked for the second time, can he still get unlocked ?

I know its weird but was wondering lol

I believe it is possible to get unlocked twice. (not sure though)
But I doubt that somebody will repay a scam just to scam again.

Pretty much the second line of this quote^.

Getting unlocked is a very long and tedious process. If and when they do get unlocked, I highly doubt they would want to repeat that cycle again like said above.

Sure, as far as I know, a user can go through the unlocking process as many times as they want. With that said, and as mentioned above, the process is very long so I don't really understand why someone would go through all of that just to scam again and go through the process..again.

Yes you can. iRowe has been locked/tagged 2-3 times already

Really I just saw that guy in gc saying he's notgonna post for awhile
