With an account on tusooa.xyz you'll be able to follow people on any Mastodon server and beyond.

As Mastodon requires an email address to register, and I think that is not a piece of necessary information, registration is now closed. Instead, please register on https://kazv.moe and use that instance. -- 鉴于 Mastodon 注册时强行要求邮箱地址,而我认为这并不是必要信息,故现关闭注册。与其在这块注册,您还是去 https://kazv.moe 注册,用那个实例吧。
