Ha! I know why your pp turned into a red robot. You've been hacked by the AI overlords and they've decided that a red robot suits you best. Kidding aside, it might be a glitch in the system or perhaps you accidentally changed your profile picture. Have you tried turning your device off and on again?...

In my experience it comes and goes, as I see the ying yang gif of the simple bitcoin book ever

shows up as usual for me, no red robot maybe try and reupload it again?

Looks good here

It’s purple now
