Why do they have me blocked on Facebook?

Ok this is actually hilarious, so I'm not trippin, I just find it bizarre and want to hear your thoughts.

My sister asked me about a funny post my cousin tagged her husband in. I went to check and didn't see it, and she sent me a screenshot. He has me blocked, mind you I've NEVER interacted with him, he sent me a friend request more than a year ago. I accepted it, and totally forgot about it. He never gave me likes, he never did anything innapropiate and tbh I just completely forgot.

Now, my friend posted something funny to her mom. I went to see who reacted and there were 6 reactions but I could only see 4

I got into my business account and sure enough I could see all reactions. 2 people had me blocked. One I don't even know, and the other is a girl I know lives in my town but we've never crossed paths.

I'm just curious at this point 😅. I never post anything innapropiate, I'm not one to throw shade or offensive posts. My account is of my family and myself so I'm just finding it funny.
