It was provocative to me. That's the problem. But you don't get that because you're not the target of the provocation obviously.
I had no issue with his signature and it was "targeted" to me as well - seeing as it was true what he said. I did not keep my promise, and I doubt he would have written your name in their if this was also not true. In any case, a four weeks ban for that is ridiculous. I haven't got banned for anything even like that, actually. The few times my signature was way worse than that it got removed (no ban followed - even none by DC).
In fact, and no offense, but you do seem to be the only moderator here banning people that say even the slightest thing negative towards you really hard. It's pretty unfair.
Now I get that people are idiots and can't shut up once in a while, but you have to stop caring about what people think of you. It's the Internet, most people don't even think before they type so stop taking it all too hard.
