This dramatic deletion is overreaction, solve the underlying problem instead.
Rather than scrolling instagram and tiktok, visit /news and /newest, and then /ask, /show. If nothing interesting there, refresh the /newest until there is. You can be first in upvoting or commenting on it, and can get a good bump to your score if you say something that sounds smart before it hits the frontpage. Then you can re-read the quality content you produced and count how much is left to the round number, like it's only 40 to 9700, only 340 to 10000, etc. Much healthier than just scrolling endlessly and sharing memes.
