in addition to depressing liquidity, Zecco sometimes has problems matching up the before/after shares with reverse splits, and may be trying to protect their back office.
I had this happen to me on another stock and have to keep calling them every day so that they don't treat my normal sale of the position as an unmatched sale (therefore a short).
If I could afford to buy all of them, I would not need to buy any of them and I sure wouldn't be spending time on the message boards!
