Whether Khaled takes the time or not, another vicous URL will just appear. Khaled has already taken the neccisery steps to prevent a user from hurting themselves, or another. But the fact of the matter is the user themself has to take responsibilty also. I mean commands such as //$decode(...) do not work any more for this reason, such as links now have a confirmation box. At some point the user has to stop copying and pasting everything a user tells them to.
Additionally, the mIRC "Sandbox" idea has been discussed, to put such commands as /dll, /run, etc into their own enviornment out of "harms way" unless the user explicitly wants to run them. You may try using the search feature, expand to all forums and all dates, and search for "mirc sandbox".
