If I've disappeared from following your site, it's not by choice. Blogger has decided to drop me from everyone else's blog. It also won't allow me to rejoin your sites. I cannot even follow my own blog. I get error messages whenever I try to access the followers moderation on dashboard.
Depending on your browser, it might look like I've kicked off all my followers. I have not. Nor have I blocked anyone from becoming a follower.
I didn't want anyone to think I was dropping them intentionally.
