Adding friction with time-based bandwidth choking/restrictions I included as a feature when creating SocialsDetox, albeit this was primarily intended for video-based sites/apps - to increase frustration with them (poor user experience) rather than outright blocking. If you think it would help, and are happy to be a tester for expanding the functionality to other infinity apps/sites (e.g. Reddit), drop me an email (link in profile) and I'll look to get something setup to see if it works for you/your intended use case.
