1. Events can be deleted using NIP 9 and I do it often in https://nostrudel.ninja

2. Adding photos issue and blurred images in the feed are specific to damus.

3. You can discover more users by using https://coracle.social and https://nostrudel.ninja as described in this post: https://uncensoredtech.substack.com/p/bring-your-own-algo

4. I don't use zaps but they seem to work for others.

5. Searching for users with NIP 5 ID or NPUB works fine in most clients.
