FAQs: More Tips About Block Someone on WhatsApp

1 Do they know when you block someone on WhatsApp? And what do they see?

A user can suspect that you have blocked them on WhatsApp if they notice that, all of a sudden, they can no longer see your profile picture, stories, status, profile, and their messages are not delivering to you. But then, this is not a sure way to tell because some users naturally don't have a profile picture and naturally don't post. And some have hidden their last seen, plus other privacy features.

Yes, you can. You can unblock every contact you block on WhatsApp at any given time. Therefore, every blocked contact is temporarily blocked.
