How many different accounts do you have to delete though? For many of those people "t" and "f" would be substituted by "y"toube, "r"eddit, etc. It doesn't have to be a social media site, might be news you're intrested in, tech sites, deals aggregator.
I get what you mean, but for someone with habit of looking for distraction whenever they have nothing to do it won't be a cure, bandaid at best.
If you care about yourself and want to have healthier and more mindful habits, you will hopefully start redirecting what were once mindless impulses of avoidance or boredom into more meaningful activities for yourself.
