Facebook posts hidden or 30 days?

Facebook posts hidden only for 30 days and not for ever?

When you set a site inside Facebook it will be full of advertising video. is it possible to block posts from source for ever as there is an option to hide 30 days?
I have calculated annoying posts. It is more than 80.

It is very annoying to receive posts which are not necessary.

I think the hide function is for the individual user. Did you want to hide from the readers of your page?

As I understand we control (admin) any posts. It is an issue when you open a Facebook site. It will be 80 posts within a short time of frame.

Check your posting setting. I think you can on fuction hide post after 30 days.
