Btw just a note, this is from my log from last year when I was KBH:ing
myself. I asked from Amarth about doing what you're now planning
(translation follows):
You tell Amarth 'saanko palkata pelaajia istumaan pellolla rivissä ja ampuu
sitä niihin'
Amarth tells you 'noin periaatteesta sanoisin että et'

translation:

Me: can i hire players and shoot melody at them repeatedly to kbh it?
Amarth: as a basic rule/princible, no.

So you might want to ask this again, has the rule changed before getting
your kbh status nulled.
