Ignoring triggers

Hi I've got some problem.
How to write a script that will stop the trigger? I got trigger for healing. I have to create array of users that misuses my help. And that users won't get heal from me. Pls help me how to do it.

The easy way (not necessarily the *right* way mind you) is probably just to add an ifcheck to the script and expand it as necessary to send those annoying people a rude tell or something instead of casting spells on them. Doing things the *right* way in jscript is usually entirely more code than it's worth in my experience due to the bass-ackwards way java was written in the first place.
