Why do I have to wait 48 hours before blocking someone again? Facebook's 48-hour waiting period exists to prevent people from abusing the blocking feature. For example, it prevents a user from unblocking someone, harassing them and immediately blocking them again to avoid being called out or reported.

You won't be able to block them again for 48 hours. Note: If you're unblocking messages and calls from a Facebook profile, you won't be able to place that kind of block again, but you can use restrict to stop seeing messages and calls from someone without blocking their profile.
