It's a grey area for me. I tend to support it when it comes to materials that are difficult to get a hold of legitimately, which season 12 of Top Gear would technically be. Materials that can be easily bought should in my opinion generally not be shared on JDMST.
That said, that's my own perspective. I don't think we've put down a concrete rule yet. Suffice it to say, if you post up a link to season 12 of Top Gear, I'm not going to penalise you for it.
