This made it easy to Google him, and it would appear that memoryvault is Peter Sawyer. Maybe that's been disclosed there before* - it is not as if I read every single thread or comment, but this is new to me.
Now, there were hints previously (from the oddball commenter Fisk, I think) that MV had been involved in nutty Right wing politics a few decades ago, and yes, I see that he is the subject of some material on the 'net. I'm not sure of the author of this piece talking about far right politics in Australia in the 80's and 90's, but here's what he (or she) writes about Sawyer:
Googling around further led me to a 2010 comment on an Andrew Bolt thread, where it would appear that Sawyer was doing a Trump - talking about himself without disclosing it:Soothsayers and false prophets made the message propagandistically immediate. Peter Sawyer, a sacked Social Security employee, became an oracle. Sawyer rose to fame upon insisting a conspiracy existed at the ‘Deakin Centre’ to use super-computer departmental linkages to re-formulate the ‘Australia Card’. In 1987 he predicted Aboriginal revolution:The real weapons for the Great Black Revolution arrived quietly in WA some months ago. 7,000 AK47 Russian assault rifles, plus ammunition. These were shipped in on false documents prepared by Fuller Firearm Group of … Sydney. Transfer of funds was arranged through Mr. Laurie Connell’s Merchant Bank, Rothwells and they are currently … stored … around various warehouses owned by Mr. Alan Bond.Panic was recorded in some rural centres. Sawyer drew large audiences in many Queensland towns and was vociferously endorsed by Sydney radio personality Brian Wilshire, who subsequently authored ‘conspiratology’ books himself. Sawyer suggested black revolution was a plot of the United Nations to permit military intervention in Australia.Sawyer’s wild tales utilized ex-CPA member Geoff McDonald, whose Red Over Black, described ‘Land Rights’ as a communist/United Nations conspiracy. ‘Pro-mining’ McDonald, who had been patronized by Bjelke-Petersen, Ruxton, the LOR and Liberal-National branches, travelled throughout Australia during 1979-85, predicting violence. Nonetheless, Sawyer’s star-gazing outdid McDonald and even Eric Butler, who denounced him.
Anyway, I wonder how many of the old timers there are aware of the extraordinary wrong-ness of Sawyer's previous political warnings...
* Update: yes, it was disclosed before, by Sawyer on Catallaxy, back in 2015. In fact, now that I read the disclosure in 2015, I think I had seen that before, but what I had never bothered doing was Googling his name to see what he was known for, politically.
