Partially blocking these vents is not a good idea.
We had a similar arrangement in our old house, the internal airbrick was
covered over in the renovations, never caused a problem.
sometimes it does, sometimes it doesnt, doesnt make it a good idea.
small bathroom fans are really hopeless anyway, and not even worth
switching on at bathtime.
not my experience at all. Had a 100mm inline van in the loft, venting
the bathroom through the roof. operated by a humidistat. It worked very
well, much better than the previous arrangement - a window. Never any
problems with damp, mould etc.
I wonder why. My 6 inch one was useless.
