By all means, let us know if you get any response.
There are stacks of threads, AVZ included, on Hot Copper with people complaining of manipulation and reporting it and asking the BOD's etc. 90% of the time this goes nowhere. The BOD's are usually aware of it and don't have much power to stop it. (from what I have seen).
Yes, it is market manipulation, but unfortunately there is a lot of it that goes on in the ASX. Especially with speculative small and micro cap stocks.
