Yes, I can imagine, but being honest with myself, they would have no interest in doing so.
First, sneaking in buybacks is a tricky thing with a mostly low-volume ticker. If you noticed 100-million shares traded every day, then maybe it could be happening, but I don't see the incentive in it.
If I were running this company from this point going forward, I would have no buy-back or reverse-splits of any kind; there's just no benefit to any of it.
What I'd do is get a killer company going with killer products and consistent growth, and let the stock climb up into penny land buy itself.
Then When the time is right to go big-board, I would reverse split 1:100 and build the company up into NASDAQ territory.
Right now, no stock manipulation makes any sense to me.
