Baffling that this needs repeating. Don't ask owned slaves to tribute. When refused, don't tell them to secretly buy items from your wishlist. Not only does it not work, it's just sad and pathetic... and anything but alpha. Be better. This community deserves better. It deserves real Alphas.
I prefer to handle it directly. Messaged the "alpha", if the problem continues I'll happily escalate things. Pretenders don't last long, whether they delete their accounts or get booted.
