I opened up my emails and found all facebook activety listed as emails. Why did this happen, I did not change anything on either my email or facebook. Thanks
If they all came from one post you can go to that post, click on the 3 dots at the top right corner of that post and turn off notifications. Otherwise you'll have to go to Settings and check what notifications have been turned on. One other thing to check is to see if your Facebook page has been hijacked. Change your password immediately and do a Facebook search for your name. If more than one page turns up one might be a hijacked one that uses photos and info from your real page. Notify Facebook and let your friends know which is the real you.
