No social media site needs to enforce restrictions on multiple accounts, the primary reason they do is to exert control over their users. Just off the top of my head a single use case: a reddit account for posts I make for myself, vs. those I make on behalf of my employer (or more specifically in my case, my wife's business). Then there are bot accounts, users who want to keep their interests and hobbies distinct. Users who have a income based off of activity on social media (and not just sex-workers, but also indie game designers, streamers, social media management folks, etc, etc, etc). You might not think that you want to keep the different "personas" that you have separate on social media, but most people do, and I say this as a person who uses a single username and profile on most social media sites. If you are in the business of designing user facing systems I really hope you take some time to learn about how folks use computer systems and user-centric design.
