Maybe not smoking so much weed might help with this.

I quit smoking weed after I had been looking for my phone under the bed for half an hour - using the flashlight of my phone.

Same thing like you did. The difference is I only edited the content and then I just left it. Deleting everything leads to reddit undeleting it. Leaving the Nonsense there did not trigger their alarm.

I just only did the first step: replace all I had written with random gibberish. And then I did nothing. Just left it there. And the gibberish is still there. Mission accomplished. One of the goals of this method was to feed KI with Nonsense. Obviously I wasn’t the only person who did so. And it looks like it has worked.
