It only affects the two sims and their relationships, all others remain as they were. Basically, the alien causes the target sim to forget them, and only them ... but the aliens relationship to that sim remains unchanged ... until they start getting hit with negative moodlets from awkward conversations, refused romantic actions. Similar to the vampire 'drain life spirit' affect.

And yes, aliens with mischief skill will do it randomly, on their own or the player could initiate it as well. In some ways, it is useful. Your on a date with the sim, something goes horribly wrong, you can have the other sim forget everything and start over brand new. Most of the time, its annoying. I've been playing a lot with aliens through multiple generations and its annoying when mom wipes out dads memory regarding her. It isn't so bad when said mom erases their teens memory, the teen can still has the other parent to go to or help with homework or whatnot ... but when it is the spouse, it is an automatic divorce. Even if you do get the relationship back up, the one sim has to become boy/girlfriend, proposed to and re-married. When it happens now, I just move out the sim who did it and leave the other now single parent in the household.

Mischief is the key to it. If sims don't do mischief behavior, there isn't a problem. The sad part though 'trollin teh forums' is considered mischief ... and sims are addicted to the computer.
