I never made that connection --- until now --- but my Facebook page suddenly became mysteriously unavailable. It was shortly after I "shared" some of my Hubs on Facebook.
I've asked for password resets, etc., --- on all my email accounts. I've check my "spam" folders to make sure the reset emails weren't re-directed there. I've done everything.
Apparently Facebook has simply "blacklisted" me. They've never even told me why, or given me a chance to fix the problem at all.
It's kind of scary, because I have many causes and lots of good information on there. I've been building up and saving all my stuff for so long now, on Facebook. I even became re-acquainted with long-lost relatives, and found relatives I never knew I had.
