I've been using Twitter since 2011 and have had the odd account suspended now and again but last night Twitter took down one of my projects, suspending 132 out of 150 accounts. Accounts were around a year old, with around 40% PVA, all on different proxies (other accounts using the same proxies are fine). All my accounts use the same domain for emails, but again 100's of other accounts that I do this with are fine. So whats the problem? I've been tweeting links from these accounts from the same domain, around 3 a day with 2 non linked tweets (in a random order). It has to be that right? Its the only other footprint I can think off.
