Why would you restrict a fam member on social media?

I think my cousin restricted me and i'm not sure why,
we are both introverts and we both know it it's been a long time since we saw each other too i have been liking many of their post and suddenly i didn't see anything new aside gaming streams and i think they restricted me from seeing their stories as well
I remember them copying certain things that i do post tho, maybe they just did it cuz i am younger than them and maybe they forgot my age and don't want me exposed to some depressing or sexual contents knowing our parents at least i hope so i don't rlly want to compete against an elder cousin or maybe i've upset them and don't know and i'm too shy to talk.
