As to your second question, anyone could use the 'emote' command to 'do' basically anything they can imagine. The target in question doesn't even have to be logged in.

I could be at the Inn at level 1 and do:
emote summons Arratok, spins him around, kisses him on the ass and then teleports him off to a village old folks home.

It's basically just poor RP, as bad as going OOC, IMHO and worth reporting probably.

As far as the age thing, I don't see the problem.

Imagine a kid's been practicing martial arts since he was 2, and is a bit of a prodigy. By the age of 15 he has 4 black belts and won 200 tournaments. Meanwhile, you just took up martial arts at the age of 35. You've been at it a year and you're a green belt.

So just cuz the 15 year old could kick your ass, doesn't mean he's not a snot-nosed little brat that can't vote, drink or even drive a car. Meanwhile the kid is thinking "get lost grampa." I'd say the elf is role playing well. This is why nobody likes elves, they're snooty know-it-alls. I'd say just give it back to them. "Maybe if you'd quit staring off into space and while singing koom bye yah and hugging trees you might actually know how to use that sword, you old faerie!"
