One reason is privacy, and I'm currently trying to figure out gpsbabel's options for doing this.

gpsbabel -i gpx -f 'test.gpx' -x track,move=-12324359s -x polygon,file='poly1.arc',exclude -o gpx -F -

poly1.arc looks like:

-33,150
-33,151
-34,151
-34,150
-33,150

But the above command doesn't filter out points in that area, what have I overlooked exactly?

Failing this I'm just going to code something up that parses the GPX file and batch re-writes them as I don't feel like doing them all by hand, I have about 173 older GPX files to process.
