To test this out, I fired up reddit.com in a private browsing session. The first four ads I saw were: a Windows 10 HP laptop, an AAA game from Square Enix, coronavirus messaging from the UK government, and a small indie game.
I checked on a computer with no ad blocker, and I see adverts from the UK Government for their job seeking help site, SquareSpace[1], Toyota[2], Sky[3], HP / Microsoft, BT[4]. You signed up a new account here to post politically divisive and trolling views on Reddit, apparently based on fantasy.
