Why IP shows in Access Keys?

[MintBlitz]

shadowsocks-libev key: ss://YWVzLTI1Ni1nY204anhSZjdQWDFdYUBtaW50YmxpdHouZ2E6NAU2PTE

outline access key: ss://[email protected]:6538/?outline=1

Why mentioning the IP and port in the key? When sharing on Chinese social media like Wechat, that sounds like a big security breach. Censors will know our servers very quickly and easily, even if the key is no longer valid. shadowsocks-libev doesn't mention it in the key
