I see your point, and you are right, Though if a newbie willingly disables the security feature, It takes some of the blame off mIRC. Ofcourse, it doesn't solve the problem of the security being compromised. Although it might stop a certain % of it.

From mIRC's perspective, If a newbie has enabled it, and ignored a clear warning, then it is their own fault. Right now, mIRC do have some responsiblity in unleashing a powerful langauge in a chat enviroment, where a newbie might not expect they are using anything but a normal chat program.
