Having looked them up, the tweets are obviously not great and it's a little murky given that he was 18, technically an adult, but based on what he's had to say about it I think there's ample evidence that he's not that kid any more and has genuinely matured/is sorry. I think on balance that it is vitally important to let people grow and better themselves and reward them for doing so... otherwise, how do you get anyone to change?

That said I think it's important to point out that he's been suspended pending investigation, which is appropriate. He has not been kneejerk banned.

On the topic of "the line" again I'd go back to it being murky because he was 18. If he'd been 15 I'd feel differently. You cannot judge an adult on things they said at 15 - ludicrous.
