I have a question and I know I am not the only one with this issue as when I asked several people they all said similar things happened to them.
The question: Why is Facebook automatically liking pages for me? I most certainly did not like "praise jesus" pages nor other "funny" pages that I just found out in my news feed. Is there anything more to this? And finally...what can I do about this besides disliking the page ?
When a page changes hands/admins, there could be some political agenda pushed, or even a religious agenda. It could be another "best vines" page, who knows?
When this happens, the page jumps to the top of a person's likes, so as to notify the person of the new page contents. Usually the page is left with no trace of previous posts. (All posts are wiped, but the likes remain)
Of course, now you're going to tell me you don't like any pages, and liked pages are conjured up from Facebook itself, which is highly unlikely, unless they are doing A/B testing on you, and you are simply a guinea pig, but again, unlikely.
This is deceptive on Facebook's part, because ... Facebook
It's nothing to worry about though. Simply unlike, and soldier on through your day.
