People in the email group bought almost a million shares...

People in the email group bought almost a million shares yesterday morning in the selldown at the low 70's. Just wondering if I should put out a general buy signal when the bot deliberately pushes the price down, and a sell signal when it pushes it up too high.
One of the uses of bots is that when there are not many in the sell que at all, push the price up much higher than is warranted like it did to 87c, then crash it back to more realistic levels, scaring people into thinking they missed the top, then doing the flash crash like yesterday. So if a big player came along and did the opposite, sold to the bot in the 80's (members of the email group did just that, and some rebought yesterday, (great trading BTW)), then we could render the bot useless by acting as a large player, hmmm.

Thoughts people? I'm thinking in a trading sense for a few shares to make money along the way at the bots expense. Just a simple buy or sell that the traders did altogether. Easy to organise with a large group that don't mind making some extra coin along the way. Thoughts? Is it legal? I suppose if I just gave my thoughts in one word via email, no one HAS to follow, they just could if they wanted too.
I don't mind killing a few bots with a couple of million (all combined) buys and sells along the way.
BTW apart from the million buys, there were no sells from the group yesterday, that I know of.
