Hello I have a few pages on facebook and one of them has about 100K likes, on this page i tag my other pages to promote them in my posts and now this week i noticed something that has never happend before, evertime i post something from my 100K page and tags one of the other pages in it the post appears on the other pages "posts by others" wich it have never done before, is it someway i can hide the 100K from showing in "posts by others" on my other pages cause it posts quite a lot and fills up their box wich i dont want :/ also, is this a new change as i have never had it happen erlier ?
No your own privacy setting will not change anything in your pages, you are correct. There might be any other reason behind this.
