Can someone who blocked you see your posts in a group ?

[abed]

So I've got blocked by someone , and it seems they can see my posts (we're in the same group) , like when I post something it's like :
Seen by :
Person 1
Person 2
Person 3
+ 1 other ....
And when I click on it , it only shows the other 3 , and my friend confiremd that they show in the "seen" section .
I'm pretty sure they can't unblock me and re-block on the same day (because you have to wait 48 hours before blocking again) , and I check for his name daily and nothing ???
Help and thanks !
P.S Im talking about Facebook

No he/she cant.

If the person blocked you, you would not be able to "check" on that person because he or she would be invisible to you.

Likewise, YOU are invisible to that person, so anything you post will not be seen regardless of where you post it.

More likely, that person didn't block you, but put you on his restricted list, or just make the account private.

Instead of simply checking for his name every day and wasting your time with that, block him. That way you will know that he can't see your stuff.
