X, formerly Twitter, announced today that is starting a new experiment to charge a $1 per year fee for “new unverified” users to interact with posts. The company said this test is currently live in New Zealand and the Philippines and existing users won’t be affected.

Users will get to post content, like, repost, reply, bookmark, and quote posts for paying that fee. New free users will just get a read-only account to look at posts and follow accounts.

The company’s support account clarified that this “Not A bot” program is not a profit driver — but it’s hard to take reason at face value. The Elon Musk-owned company said that this program will help it reduce spam.

“This new test was developed to bolster our already successful efforts to reduce spam, manipulation of our platform, and bot activity while balancing platform accessibility with the small fee amount. It is not a profit driver,” the company said.

On its support page, the company said it will share the results about how the program’s effectiveness to battle spam.

The move comes after Musk said that X is planning to charge users “a small monthly payment” to use its service. While the payment in the test program is annual, ethos is the same.
