@Moon I have always thought it was a bad idea, since it's inception, no one was listening: "Hurr-durr, but it protects me against DDOS"
TBH, it was indeed bad at the time: a bunch of teenagers making requests over DLS could take your website down (LOIC or whatever?), I think you could make a Windows machine unresponsive with tcpdump over LAN — fun times 🤣
But this was still a bad idea!
