Its all about political correctness. The mice men out there don't want anyone shooting at people shaped targets.
So, many clubs and even police organizations have switched from the silhouette to the more impersonal and correct center mass target which looks more like a coke bottle than a target.
Even the BlackB27 police targets in some places have been changed to the dark blue ones....we can't have people"preconditioned" to shoot at black targets now can we?
In some places, common sense is still apparent and such foolishness is not tolerated. For the rest of the world where mice men rule, shooting at ANYTHING is highly discouraged and will continue to be so.
