What are you thinking through here? Are you still arguing in favor of deleting?
1. I didn’t understand this point very well sorry. But I didn’t know it was possible to insert events in the past. (Am not a developer). Interesting.
2. When you say the attacker can start deleting, does that mean that there is already some functionality that allows deleting (and actually guarantees it)? I thought as of now it’s impossible to delete.
