seems that facebook limited the amount of post number to groups to 50 per account? if you exceed this you will be restricted for posting for up to 14 days. i tested it with 10 accounts. posted manually with 5 of them and used a bot on the other 5. the posting delays were different on all of them. from 60sec to 300sec. result: posting to 50 groups with no problem. restriction after the 51th post.... do you guys experience the same?
