I've tried to follow and unfollow on the same time. It was work perfectly on the first days, because I setted "Unfollow after 3 days". Starting with day 3, I had like 100 unfollow and 300 follow, even I set both at 500. Now I let only the unfollow task on FL, with a limit between 600 and 800. I'm getting annoying captchas all the time. Which are your unfollow settings guys?
