How can you see the profile of the person who blocked you?

How do I find the people who have blocked me on Facebook? Assuming that these are people who are or were your friends on Facebook then try remembering the number of friends you have. Usually you'll see some difference with that, especially if the one who blocked you is a close friend. Try viewing your previous messages with the said person if you can retrieve those.

If it's just random people on Facebook then it's hard to guess who. The article I have attached below in this answer is very helpful in cases like this. Kindly read it for your reference.
