My take on these things is as follows, for what its worth...
Daz (badly) launched an attack (initially thought to be at a whole thread) at Ljay, with the deliberate intention to provoke a response (aka bullying)....and he got one.
Ljay did her best to sort in private, but he refused to speak to her and he carried on provoking.
Alert Mod had been used, I perceived him as the instigator and trouble maker, so implemented the short ban.
IF he hadnt deliberately been provocative, none of this would have happened. He believes however he has done nothing wrong.
An analogy....If one of your wives, girlfriends, sisters etc were being raped....and in their defence, punch, gouge, hit at their attacker....would you punish them, see them convicted of assault etc? No. you would be up in arms if that happened. IMHO the same principal applies here.
If you disagree with that, I will discuss further privately if required.
