I had an account on reddit, about five years old until I finally decided to leave it because i spend an ungodly amount of time there. Knowing myself and my habit to flake on self set goals I thought out the ultimate strategy to keep me from coming back: Over a couple of weeks I intentionally posted atrocious stuff on my main and my two alt-accounts to get me permabanned and burn every single bridge.

For now it has successfully stopped me from wasting time there any longer.
