I was getting a few hundred followers a week, sometimes in a day. It ended at the first of the year. I am lucky to get two a day now. I think something has been governed by Facebook as the new owners. It is obvious the algorithms have changed the growth for some reason. They are not affecting all accounts, only select ones. I don't post anything except art work and associated things to it. I stopped following several people because of political posts. That's the only change in the few years I've had the account. The unfollow coincides with the timeline of my account seeming to be frozen.
