Could well be. I do remember some reviews of certain Marin full sus bikes and people saying that the rear end wasn't as stiff as some, but can't remember which years. I guess around 07/08.
The fact that it only does it under pedal power points to a worn linkage or flex in the frame. However, if it wad the later it would have done it from day one. The fact that you've done a fair few miles makes me think something has worn.

^^^^^ actually that pretty much rules out any calliper pad/piston problem. when ridden, something is twisting enough to cause the pads to rub against the disc.
are spokes on rear wheel tensioned both sides?
do you have another rear wheel to try out?
get hold of a whiteboard marker pen and scribble on the disc, ride the bike so that the disc rubs but without applying rear brake - then look at the disc where the marker pen ink has been rubbed off - that will show the direction of the flex.
TBH I doubt changing seals or taking it to LBS will sort it unless the LBS can make you a stiffer new swingarm. <--- that's still my theory.
