Twitter has again made its platform a little less usable for people who choose not to pay for a Blue subscription. The company has announced that it will soon implement a new rule that puts a limit on the number of DMs unverified accounts can send per day. In a tweet, Twitter said the change is part of its efforts to reduce spam in direct messages, which has seen a sharp uptick recently. 

On July 14th, the website added a new message setting that sends DMs from accounts people follow to their primary inbox and DMs from verified users they don't follow to their message request inbox. Twitter said it saw a 70 percent reduction in spam messages a week after the new setting came out. Before that, the website limited the ability to send DMs to people who don't follow them to Blue subscribers only.
