I've thought of doing that before too, but it felt like sending a robot to the North Pole to get my presents from Santa, without even a cookie. I don't think it's necessarily abusive though, unless you are requesting more buffs than you use. If Mr. Kinks wants to, he can easily stop mafia from accessing KoB since mafia clearly identifies itself. Hopefully, scripts will never abuse his service to the point where that is necessary.
If you do that, I'd recommend scripting in a donation to KoB too.
