It seems that I ignored someone and I have no idea how I did it or how to undo it. I've looked around in my profile settings and don't see anything about ignoring. Thanks!
I found this when I googled it. Hope it helps, well unless I'm the blocked and you can't see this
The "Ignore" feature allows you to block posts from a particular user. You will still see a line that indicates the existence of a post from the user, but you will not see the contents of the post. You can ignore or stop ignoring a user at any time.
Click on the user name you wish to ignore (in the left column next to the post).
In the user's profile, click on Ignore (in the right column above the member bio and list of most recent posts).
To stop ignoring a user and read his/her posts and PMs, click on the user name next to a blocked post to access the user profile. From the profile, click on Stop Ignoring.
