waht rubbish is this

Firstly a bid for 1000 shares worth $42 is placed before open at .042 which goes through on open. Then a bid of 160 worth $6.40 is placed at .04 which 1 minute later goes through at .042 for $6.72. Then a minute later another 160 share bid is placed which a minute later goes through at .042 for $6.72. Then another of the same goes through a minute later. Another one of 160 has hit the bid line at .04 as I write and just gone through at .042.

Now 100,000 has hit at .040 on the bid.

What rubbish is this?

Anyone care to have a go at explaining why such small transactions would go through?
