If someone changes a Sign Text he were kick, with the reason "Exploit." And in the console is Code: 19:50:57 [SCHWERWIEGEND] Player RaymanMaik//127.0.0.1:43520 just tried to change the sign text at 20,69,36 - very likely an exploit attempt. Recommend ban, and sending a package of joy their way. How can I turn it off?
That is built into Bukkit, it's to stop people from using an mods in the client to grief signs. I don't think there's a way to turn it off.
Yes, it is with using the "Neocrafter Mod" (german). @Bukkit-Team: Can you please make it possible to turn it off?
