Not that I'm trying to stand up for them, but that's not an uncommon approach to making it work.
Lots of blocks don't have threads that go deep enough and I know of many guys that do that. It's not a big deal, really, it's just a hunk of steel. It's best to chase the threads with a bottom tap, but if you don't have one (lots of $$$) then grind a little if it makes it work out better.
