I think there's a kind of bot with followers every time a post is made, it really happens to me that in every post I get at least 20 @ginabot notifications from new followers, which mostly have the same time, reputation and sp, I haven't received at least one comment and at least one positive vote from any of them, so I don't think they're real followers, but in the end what counts is that your followers are loyal, so much or little, I know that many support your content, congratulations on your new number of followers.
