I don't recall reading or hearing of this happening, but I can't be sure. All I know is that AP holders, DVC members and Disney Visa Card holders often buy tickets for guests, and probably for friends and family who may go separately. It's a common thing, I would imagine. In the past, I don't recall Disney cracking down at the turnstiles, and making sure that everyone with an MHP ticket was there with the people who actually bought the tickets, but that doesn't mean they couldn't begin enforcing it. They are trying to thwart the efforts of people trying to buy and resell their tickets, and they may start getting a little more restrictive in some ways, or taking precautions to make sure that everything is on the level.
I didn't see what the hard tickets looked like in 2014, but in prior years I don't remember hearing about any special Halloween print on them -- I could be blanking out. I think they were kind of plain. I had e-tickets, but I recall seeing some tickets at some point, and they were not decorated.
