That MrX_ASX was clearly a troll account. I flicked a couple of messages and after them I was still happy to call it a troll account afterwards. I haven't seen a dump of 23m shares anywhere and I doubt anyone would buy them for that much considering they can be consolidated at a lower price.
Why would someone create an anonymous account just to try and flick off shares? Because you're not trying to flick anything it's because you want people with loose hands to let go of theirs.
If you want to post things with obvious holes as an exertion then don't expect to have any credibility when you post in future.
