$4 trades in motopia

I'm a new holder of Motopia shares and recently I've noticed a flurry of @$4 trades at 0.002 each day after respectable trades at 0.003.

It would seem pretty obvious this is an attempt to force the trading price down.

I'm just wondering if this would really have any effect?

From my position it's very transparent but maybe not so apparent to others?

And out of curiosity....each of these trades [20 plus per day] would be attracting a brokerage fee?

Thanks :)
