i think your last sentence is what makes it all right. parents that just log all their kid’s activities just b/c they think they’re watching pr0n or whatnot and don’t do anything further than ground them or what have you, are not solving the problem at all. so no, i don’t think what you’re saying is going overboard. i would start out with just keeping an eye on what they’re doing, then if suspicion arises, use a keylogger.
