How Twitter is fighting spam and malicious automation

Twitter fights spam and malicious automation strategically and at scale. We are removing 214% more accounts for violating our spam policies on a year-on-year basis. In Q1 2018, we suspended more than 142,000 applications in violation of our rules. In the coming weeks, we will have more to share about additional steps were taking to reduce the impact of this sort of activity on Twitter. Weve also seen a 10% drop in spam reports from search as a result of our recent changes.”]
