I'm playing on a lot of servers and noticed russian hackers having creative mode without any permission.After getting in contact,we found that they use a client with a exploit from OpenMods to give creative mode to anyone [1.7.10].While this is a complex subject,the least I can do is to give a warning. https://github.com/N1nt4nd0/Xenobyte/blob/master/src/main/java/forgefuck/team/xenobyte/modules/OpenCreative.java This page contains the code of the exploit,and it looks to work on any 1.7.10 forge server with OpenMods [Includes stuff like Thermos,KCauldron etc].
