Outdated information is not malicious in nature because the poster may genuinely believe he is correct but he is just misinformed.

Example is those people keep saying 3k starting pay, obviously is from a quite a few batches ago.

Fake information is those people who say 6k starting pay out of nowhere lol.

Then misleading information is those people who say 4k starting pay which is correct for some department but they never clarify, other people misinterpret think referring to audit, and this miscommunication causes another argument lol.
