They call me Mister Nuke. You, my fine acquaintance, may call me Mister Nuke. Welcome to the wonderful dystopia that is my user page. If you're here about something I may have done to upset you, do not waste your precious time sending me a message. I will not reply. There is a good chance it was not really upsetting and that you are angry over nothing. If it was a "big deal," then well, my bad.
15 000 K/D is impossible without mods. Unless you mean they have 15 000 more kills than deaths. More than I have, by alot, but still not entirely impressive. Seen people with 50 000 more kills than deaths.
