Why can I not write any post and comment on someone's page?

[Edward]

I got onto Katie Ledecky's fanpage on facebook, but
recently, I cannot write any post nor comment on her page.
Was I blocked? Was I kicked out?
Did I do something wrong?
Or the number of posts or comments that each person can write
on a celebrity's page is limited?

I am really frustrated and upset about that.
Could you give me an answer for that?

If you Can Not Write On her Page Either She Banned you From Posting or She has Turned Off Her Wall So Nobody could Write on it if other People Can Still Write it Than you Been Banned Most Likely
