My flying letter was stolen, and someone used my flying letter to send a lot of abusive short messages to acquaintances. How can I find out who stole it?

Fetion doesn't know much about it, but I'll help you find a way. First, find out the ip of Deng Lu. Find out where the IP belongs. You can check it in the local business hall. I don't think it will help you. Give it a try! You can also use some network technologies, probably not. As for us hackers, we don't usually do things like that. It's not our purpose or the leisure, so it may be someone around you. If you carefully analyze the content of the message, you may reveal some clues ~
