Hi Johnboy,
I never had the chance to visit chnlove headquater so I have no idea of how their credit system runs. Shuan made better advice than I can offer. As far as I know, chnlove will never itself do any sneaky things in such a clumsy way. It's probably a flow or accident. We agencies suffered from their technical breakdown from time to time too.
As to the 6000 limit, it's a little tricky but you can't call it a lie. From the point view of a man, I just wonder with the update of internet and hard-drive technique, couldn't the limit be updated simultaneously? From the point of view of a former chnlove translator, what? 8000 this year? 10000 next year? ... Kill me!
