Letting him play on any server other than Toj's, I'd say most definitely no. The main reason is the sprays (Fish has sprays enabled). Quite frankly even if it is a moderated server people WILL put pornographic sprays up if enabled (our server has them disabled).
Yep. One of the first changes I made before opening the server last November. I knew, from past experience, people abuse sprays given the opportunity. And once you see something, you can't
un-see it.
(I'm still slow on the draw though :/).
Have no fear, young Padawan. One day you will be able to permban griefers as quickly as this Server Jedi.
I've been doing the Server Admin thing for several years now, so I can guess when a player is going to cause problems. I used to be more lenient, but I find myself handing out permbans to players who immediately start griefing (e.g. spewing profanity, mocking Christianity, baiting admins, etc.) without a moment's hesitation.
Of course, to permban multiple griefers simultaneously, there's nothing quite like
HLSW. <3 for HLSW.
Back to the topic at hand: Remember that while we see the blood and gore in TF2 as no big deal (thanks in part to the cartoonish art style), a young child may not yet be desensitized to such imagery. If you want to give the young one a try at TF2, I recommend finding a way to enable low violence mode. (I'm thinking of trying it out myself, as long as it doesn't mess with file checking for competitive play.)
If you can't disable blood, gore, and mature taunts in TF2, you might want to consider picking up two copies of Unreal Tournament 2004, disabling mature taunts, and lowering the blood/gore level to the lowest setting. With these simple changes, UT2004 goes from a M-rated game to a T-rated game (in my opinion; the ESRB gives ratings based on all content available).
