A month ago I felt pulled to look at the account of a new subscriber and I noticed it and two other recent subscribers each had email addresses that used the phrase everydayexplorer as part of their address. I mentioned it to a friend and she said that's a site that steals content and posts it as their own. So I blocked those subscribers. Since then I started examining the accounts of every new subscriber and have blocked several that were new members with very large numbers of followers and following and that publish many stories a day. I block those accounts as well. I haven't examined the accounts of followers but I would imagine there too are lots of bots etc. Shady subscribers seem more dangerous to me than shady followers and less daunting to examine. I have about 80 subscribers and over 2500 followers. If you have a shortcut for examining and purging, I'd love to hear it.
