Holding 'escape' to stop triggers?

[Yen]

I'm not totally sure what the extent of this is, but..

Lately, I've been having problems with players holding 'escape' to prevent death. While they're holding escape, they don't register triggeractions.

I've also heard of people holding escape and doing something to cause it to trigger the attack function multiple times. They do this when killing people and it seems to trigger the death over and over, so I'm assuming it cached the triggers and sent them all at once.

Finally, people are holding tab and D to auto-mine or auto-attack. It prevents the 'keydown' and 'keydown2' function from being caught, so the NPCs think that the key isn't being held though it is.

Can anything be done?
