The problem is there are too many posts going out per day. I limit the number of posts to 2 per day. Google Plus will also do the same. they will delete your account for more than 5/day. Nextscripts should really have a option to specify a max posts. this should be at the social network level (not global). I had requested this in the past and i am still waiting to hear back from support
I lost all of my Google plus, a few twitter and facebook accounts for this reason. I currently use Hootsuite.com which is free and you can limit the number of posts/day. No problems since. Also the way the Google plus and facebook posts shows up on the social account when sent via hootsuite is also very decent
If you dont limit the number of posts you are asking forn problems which will result in account deletions
