I'm going to comment on this one issue, mainly as there is a side that isn't seen. Though in the future don't expect a justification for each lock.
Many threads are indeed being locked regarding this new rumored threat. There are various reasons for that, and the locks are indeed correct to occur. Hacking issues generally don't belong on the forums. Most of the threads that were locked do nothing more than demand something be done. They do not discuss the issue, nor do they mention anything about the problem other than the users demand for Nexon to investigate the issue.
In the first thread created on such a topic, I noted that I have brought this up for the other Forum Mods and it's up to them if they wish to pass it on or not to be investigated. The Forum Mod's aren't the ones who look into hacking situations. While they have a bug/glitch section, that is for bugs and glitches, hacks are malicious exploits.
There is no reason for multiples of these threads to exist, or multiple discussions. I've left a few open that were intelligent discussions, but made notes that the rumors are not confirmed, and that it may prove to be a hoax in the end. This lets people talk about the issue without having these forums flooded with what some may call warnings of the plague. This simply causes fear which at this time, is unwarranted as the hack has not been confirmed.
PS: Even though a thread is locked. it can still be read, which allows it to still serve as a warning.
