"This sh*t has gotta stop," read Armstrong's post.

"One thing is for certain though, this isn’t guna [sic] stop us speaking up or stepping up."

Advocacy sees Armstrong targeted

The Barrabinya man recently voiced his support for Donnell Wallam, the national netball star at the centre of the sponsorship furore involving mining company Hancock Prospecting.

Ms Wallam expressed reservations about bearing the company's logo on her uniform, given founder Lang Hancock's racist views on Aboriginal people.

Speaking on Channel 10, Armstrong defended Wallam while questioning sections of the media which had supported the company's current owner, and daughter of Hancock, Gina Rineheart.

'The pro-Gina PR push has gone into overdrive with article after article about Gina's philanthropic niceness,' he said in a piece-to-camera.

'What they really mean is money talks. Gina throws money at things to win them over,' he said.

The email Armstrong received specifically called out his appearance on The Project, and defended Ms Rineheart.

The ABC has reportedly notified the police of the incident and forwarded the email in question to them for investigation.
