I was booted off FB during May for 'suspicious activity' - I knew I hadn't done or said anything bad, so assumed I had been hacked. No matter what I tried, I couldn't get back on - my account had been well and truly locked. In the end, I had to create another email account and start from scratch using the new email address.
The funny thing was, I thought I hated Facebook, and only kept on it to keep in touch with family members; but I really, really missed it. I missed my cat groups, my nature groups and history groups, as well as friends and family. So relieved to get back on it (at the same time wishing I wasn't bothered!)
