Ive had to bad experiences when 50+ accounts got disabled in minutes and only thing linking was posting times. Also talked to a few guys and they have had similar issues.
Haven’t had an emails verification, phone verification or captcha on any of my slaves in about 6 months. So, will keep to my strategy just incase
yes they are necessary at one point either from main or slaves but with the right settings, proxies…etc you should be good and without any issues for a long time
Try not to make it obvious that one single person is running all the accounts. If IG detects even the slightest similarity between posting schedule, pattern and post type between accounts, they’ll block them instantly.
