Yes, thank you, I'll go check these cache things again. It had just occurred me looking at the logs that / wasn't being cached on Cloudflare, but I thought event and profile pages were.
But I didn't mute nostr:npub1a6we08n7zsv2na689whc9hykpq4q6sj3kaauk9c2dm8vj0adlajq7w0tyc and I haven't received a DM from him in ages, so I don't know why he thinks that. Anyway, good ideas, I'll try them.
Now I don't think njump.me should be anyone's cash cow. It shouldn't even exist, and hopefully in the near future it will stop being necessary with browsers and other websites adopting "nostr:" URLs natively or something like that. If it dies today it will be sad and mildly disruptive, but not a fatal blow to anything.
