He is still following his ex social medial accounts. What does that mean? 10pts?

My crush broke up with his ex 6 months ago.
His ex unfollower all of his social media accounts. However, he is still following her Facebook, twitter and instragram.

His ex is following his sister's instragram. Today, his sister posted the picture of him and her together in the Christmas party. I saw his ex liked the picture.
She liked only the pictures of his sister with him.
She also liked every single pictures on his own instragram

My question is:
Does he still like his ex if he is still following her social media accounts?
Do you think she still likes him?
P.S. His ex is friend with his sister.

You ever can tell what the Ex is thinking when he is following her on the social media

[Someone]

i think she does or just basically because his sister is her friend but she might still feel something for him
And maybe he is just wondering what his ex is up to because if she's his ex
he might be mad if she has really quickly a new bf and he just wants to keep an eye on her or something
it actually could be anything , only they know

The most interesting thing that anybody posts on any of those sites is when, and how much, they peed last time. Actually, that's about the only thing they post. Perhaps she has more interesting toilet habits than you do.

The fact that he even uses "social media" indicates that he has neither a brain nor a life. Pity him but find yourself an actual boyfriend rather than a crush.
