A way to hinder interstellar portalling? FTL travel

So I'm working on a story that at its groundwork has a lot of sciency things, and then has a lot of unsciency things attached to it. The story has an FTL drive which is the good old "fold space, puncture space, travel through" methodology. As a restriction, folding more space (i.e. traveling farther) requires more energy, and smaller folds are more efficient as you fold less "extra" space. For example: If you travel 1 km, you fold 1 km of space in all directions. If you travel 10 km, you fold 10 km and thus a far greater volume.

But now I want to create an interdiction method. My current idea was to use mass and its gravity. Any mass bends space around it, and something like a planet bends much more space, which is how light can change its trajectory by a mass without actually having a mass to be attracted to the planet's mass. By causing tons of these bends in space in quick succession you could create ripples in space that go outward at the speed of light (at least I think that's the case). My idea was that these ripples would disrupt the accuracy of someone trying to bend space and trying to portal somewhere, as long as the ripple is going through the space they are bending. My question is, would that assumption be correct? Or does the space-bending properties of a mass not reach very far?

For those who realize what I'm asking, yes we are ignoring the fact that you are now creating tons of very temporary artificial gravity wells that would probably have to range between a planet's mass and a black hole to have any noticeable effect and would undoubtedly destroy your ship when you create so many nearby.
