Here’s a tricky one—If I block someone on Facebook, will they know?

Melisa: Here’s a tricky one—If I block someone on Facebook, will they know? Blocking someone feels final, but does Facebook actually let the person know? And what changes for them once they’ve been blocked? Drake: Nope! Facebook doesn’t notify people when they’re blocked. However, they might notice if they search for your profile and can’t find it or message you and can’t reach you. It’s a discreet feature. They might search your profile from another account and see everything is normal so it would indirectly convey to them that you blocked them.
