Twitter rolled out a policy on Sunday, 18 December, that rattled several of its users. The proposed policy would have disallowed:
Accounts created solely for the purpose of promoting other social media platforms
Tweets containing "free promotion" of other social media platforms
Content that contains links or usernames of other social media handles
However, it would have still allowed:
Ads promoting social media platforms
Cross-posted content from any social media platform
Users who violated this policy risked getting temporarily banned from the platform.
Facebook, Instagram, Mastodon, Truth Social, Tribel, Nostr, Post, and Linktree – these eight platforms were named by Twitter as being impacted by the policy. But other prominent social media apps like TikTok, WhatsApp, WeChat, and Weibo were conspicuously left off the blacklist.
