It puts severe strain on the bearings, in particular the rear bearing shaft which often wears right through the phosper bronze bearing then slices itself in half by wearing against the back of the cabinet.
You can see the rear bearing by removing the grey plastic cover at the back. If you get a large amount of black dust falling out then the rear bearing is goosed.
That which can be asserted without evidence, can be dismissed without evidence.
