You can hit “details” and then click “ignore the risk” and still get to https://qanonposts.com/. I did a while ago and just tried again, just have to “ignore the risk”. I also made the statement (clicked something or other) and said it was NOT deceptive etc. Figured “they” know about my little old self already and who cares.
Earlier when I tried that (clicking ignore the risk) the screen would just go blank for a second and then it would return to the first warning screen. Now it lets me through.
