Guys. The following is all you need to know about this subject:
1. If you have a higher ID you most likely bought the game at a later time. This doesn't mean you are some 8 year old idiot who should be taken outside and shot. Sadly this is often the case, leading to the common disprespect of high ID's.
2. If you have a low ID you can still be an idiot/douchebag/dipstuff. I've seen people with ID's from 400 - 6000 (Yes... low to rather high) that are complete and utter idiots and too, deserve to be taken out in the street and shot.
The point: When someone joins your server, you press F2, and see a 10K ID, wait until they say a few things before you judge. If they say "Hailo I r haz amdin plzzz. I ma speshjal ind a fwent," you have every right to use the ban hammer. If said 10K ID uses full sentences and decent grammar, don't disrespect.
That is all. Have a nice day.
