How to notice a griefer 101 (Helper guide)

[Aboxofdonuts]

Honestly, the whole lots of numbers thing is true for almost any game you can think of.

I remember playing old fps games, and 9 times out of 10, when someone logged on with a name like "ipwnnewbs218378938913" "1shot1kill1231321321" "imnotahacker777777777777", they would start hacking or aimbotting. (same with hex names)
Seems like the same rules apply for Minecraft.

I'm always leary when someone logs on with a name that seems like it wasn't thought out very well. Is it every single person? No obviously not, you still have to give them a chance.
As for not talking, I don't talk most of the time, and I know some players that log on might be from countries that speak neither English nor German, making it impossible to communicate.
