Ban? or no Ban?

[MoviePropMaster2008]

I actually temporarily banned Moviemaster1993 (1993 which probably means he's either 16 or 17 years old) because of his response to my initial query as to whether or not he was a foreigner (his English was pretty bad) and I pointed out that being up front in your User Page that English is not your first language, warns us ahead of time to be extra patient with any bad writing on the user's part. The exchange rather degenerated into this:

typical fat american gun-nut post of course i'm oblivious i'm new to the site you moronic tool you cannot ridicule my typing i have just got my first qualification in i.t i know the keyboard blindfolded

but i have to congratulate you on being the worlds first american with an extensive vocabulary

1. my details are private i like to keep them restricted only to me

2. i am english you have no opinion about linguistics when you cannot pronounce a simple word like tomato correctly 3. even though you are the moderator of this website your impression of control is similar to that of the nazi's, there is no need to be tyranical it is a simple website about guns which not to make me sound hypcritical is a bit geeky

TYPICAL AMERICAN HICK, CHICKEN FUCKING, GUN USING, OVERALL BRANDISHING BASTARD!

plese take one of the many guns you own and shoot yourself in the head with it it will make the world a better place with no americans shooting canadian soldiers in iraq ' by accident' your country is a refuge for warmongers and the overall voice of the average cunt

you people make me sick

Violation of IMFDB rules? (I thought the request to blow one's own brains out was borderline threats but you guys make the call). I don't think I was out of line when I wondered if English was NOT his native language, but he really took offense. I figured he's just such an idiot that IMFDB would be better off without him. Thoughts?

Lift the ban? Or not.
