It seems like I remembering hearing someone else say that lately also - could it be the server - I don't know much about that kind of stuff and on I do not have the followers on the sidebar like you do - I would think with that amount though it would have something to do with blog server?
Hi Sandy.... don't panic.... I don't think it is you. Blogger have changed some settings which means that some of your followers will no longer be able to follow in the same way.... you will have to ask them to sign up to email or to sign up for a google+ account. I have attached a link below where blogger explains what it has done.... hope this helps! Christine xhttp://buzz.blogger.com/2015/12/an-update-on-google-friend-connect.html
It's not your fault. In Jan-Feb, blogger blocked all followers that follow with Google Friend connect. http://buzz.blogger.com/2015/12/an-update-on-google-friend-connect.html I lost several followers, too.
Google changed something with the Google Friend Connect. You have more followers than you really know, so don't worry about it. I follow most blogs through email or Bloglovin. Those who follow blogs via email aren't counted anywhere that I know of. It's all good!!! Have a happy day!
Hello dear friend. I also lost 20 followers in one day (January 29th) due to Goggle's decision to block all visitors who don't have Google Accounts. All of Us blogspot.com Bloggers Lost A Number of Followers.I am so sorry this happen to you too. Google Blogger left an announcement about this in the Design/Settings/Manage section of our blogs. They called the change, "streamlining."
The same thing happened to me....makes me sad
