The company has outlined its efforts to make things better for its users and claimed they discovered and questioned 9.9 million accounts for spamming or being automated.
In a blog post this week, the company also added that daily reports of spam dropped by 8,000 to 17,000 between March and May this year.
Twitter's blog post read: "Due to technology and process improvements during the past year, we are now removing 214% more accounts for violating our spam policies on a year-on-year basis.
"At the same time, the average number of spam reports we received through our reporting flow continued to drop -- from an average of approximately 25,000 per day in March, to approximately 17,000 per day in May.
"We've also seen a 10% drop in spam reports from search as a result of our recent changes. These decreases in reports received means people are encountering less spam in their timeline, search, and across the Twitter product."
The company also outlined for ways it intends to continue battling spam and malicious accounts.
As well as reducing the visibility of suspicious accounts and improving its signup process, Twitter has also vowed to audit existing accounts for any signs of automated signup.
The team also promised to expand the malicious behaviour detection systems.
