Working with our industry peers today, we have suspended 284 accounts from Twitter for engaging in coordinated manipulation. Based on our existing analysis, it appears many of these accounts originated from Iran.
As with prior investigations, we are committed to engaging with other companies and relevant law enforcement entities. Our goal is to assist investigations into these activities and where possible, we will provide the public with transparency and context on our efforts.
Since our initial suspensions last Tuesday, we have continued our investigation, further building our understanding of these networks. In addition, we suspended an additional 486 accounts for violating the policies outlined last week. This brings the total suspended to 770.
Fewer than 100 of the 770 suspended accounts claimed to be located in the U.S. and many of these were sharing divisive social commentary. On average, these 100 Tweeted 867 times, were followed by 1, 268 accounts, and were less than a year old. Examples below. 
We identified one advertiser from the newly suspended set that ran $30 in ads in 2017. Those ads did not target the U.S. and the billing address was located outside of Iran. We remain engaged with law enforcement and our peer companies on this issue.
