Just my luck to miss the unsavoury stuff.
Seriously though, you’ve either pee’d in someone’s cornflakes or someone has too much time on their hands.
I’ve been out of the IT game for a while, so dont know what has changed out there, it is constsntly shifting.
But to use multiple IP addresses is on another level of malice. I dont know how easy it is to do that nowadays, but it used to be quite difficult.
We had a game server many Moons ago and there were cheaters who used to come on and we could spot them right away and kick them off the server.
We used to tell them why they were getting kicked and they would reply with “I.ll be back next round, you cant stop me”. We let them think that. All they had to do was change their name and they could get back on next round.
Unless we IP banned them….they never got back on. We didnt tell them we IP banned them, just let them think they could change their name….
But, in your case its someone messing around, they THINK they can win, but nope – they can not.
