To be honest, if someone is silly enough to keep buy or sell orders up when a TH as important as this one comes up, they can't really blame anyone else other than themselves. No one can claim ignorance to the bad news as the TH was made and gave them a whole day and a half to read what was about to be announced (possible success or failure.) If people are blindly leaving orders up and not reading the announcements made by the company - that's their own fault. It shouldn't be up to the ASX or the company to have the buy/sell lines wiped every time a price sensitive announcement is made.
