如果想保存自己所发的全部内容，最好在一开始就建立一个私有的Relay，比如建立在NAS上。
配合Docker这其实并不难，但是的确有一点门槛，对于用群晖等商业NAS的用户，需要等待厂商支持相关的Docker Image.
Anyone still wondering what the hell NIP-57 is, here's an explanation: https://github.com/nostr-protocol/nips/blob/master/57.md
TL;DR:
This NIP defines a new note type called a lightning zap of kind 9735. These represent paid lightning invoice receipts sent by a lightning node called the zapper. We also define another note type of kind 9734 which are zap request notes.
Having lightning receipts on nostr allows clients to display lightning payments from entities on the network. These can be used for fun or for spam deterrence.

如果境外relay和iris.to这类web客户端全部被墙，仍然可以自己在境内建立一个relay，召集自己的小朋友们都加上这个relay，那么这个就像是一个微信群，只有你们几个在里面发言。当然，这事最好在被墙前，通过nostr私信告知。
境内建立的relay，如果公开发布，也存在被拔网线的风险，那么就境内服务器用vpn来连上。至少国内走openvpn应该问题不大。或者建立一个内网nostr服务器，然后大家用zerotier或其他方法打洞，能连上即可。
至于境内或内网自建的relay，如果也想看看世界的信息，可以用relay broadcast，把世界上relay的信息弄过来。当然这事离不开梯子。
Maybe ban IP is not a good way, there is the AI method to recognize spam content, ban spammer pub key if they send content fulfill the model.
That makes damus.io looks like Google in early time.
How do you run relay on CF?
