My only beef with the whole thing is finding people that don't cheat.

I don't use dats and I don't want to. I was interested in the event, and proposed several times to start a group that aims for Level 80 Key Items...

But no one is interested in that.

When groups blatantly talk about cheating openly in party chat... I don't go with them again.

I'm for adjusting the difficulty by adding/changing:

1) "Floor jumps" (purchasable?)

2) Lamp adjustments. (The bullshit pause after you correctly solve them needs to go at the very least)

3) Starting the timer on Floor 1 (not the 20 seconds while your screen is black and the 10 seconds before you can move...)

4) The Key Items needed for gear needs to be reduced to 5 instead of 25.

As far as bans?
I know it'd get rid of nearly 100% of the 'problem children' on my server, and that'd be awesome.
Unfortunately it might nail a few good people that were either helping out on what they thought to be a legitimate run that wasn't; or people that went on a run that turned out to be illegitimate, but were too nice to say anything or leave (or did but after the first run).
