Oh, you mean Hordecore is still posting? last I saw he hadn't registered a character.
You said people posting from mules, many of us post from mules and do nothing negative towards the forums. You are picking one person that posted ages ago and trying to base an argument off that, he might of been banned for all you know.

It helps a lot, because people who hide behind a mule are basically known to be full of it. Look at that melee SMN guy for instance, and as I said, Hordecore doesn't even post anymore and never registered a character, that alone was worth it.
Many post from mules as I say and post lots of things on here that have nothing bad to be said about them, many which offer as valuable contributions as everyone else. If you want to make an argument against mule posters/hide feature then you have to show that people that would use it would be any more negative than the norm, of the small number of posters you can show that were bad "in the past" they should of been the people that would of been best suited to being banned.
