Pretty sure it's a purposeful removal.

People that could post were making 19 spam lords on the other servers and then spinning their amulet thereby posting it 20 times on the same FB account for alliance members.

Obviously if you put forth a bit of effort with some friends (that were Prinz) you could easily get 40 amulets a day. Hardly balanced.

I DO know that it was not common to be one of the select few that could post amulets. Those that could definitely abused it, though.
