Many methods can improve loose posts but I prefer epoxy and disagree with whoever said it is always a bad idea.
The thing with loose posts is that almost always they can be easily rotated to both directions from their correct position (usually just slightly to close more). Making the threads a tighter fit without glue means the post is still not stopped by the end of the rotation, but just friction in the threads. Teflon tape is often used to reduce friction for the tighter fit it creates, but also mainly to help seal. IME in these types of situations it compresses significantly over time (or maybe a better description is that it is pushed to the "sides") so less likely to remain secure. There are constant forces the spring pushing or pulling the posts slightly.
Epoxy is easily reversible if necessary, though I'm not sure if I ever even needed to remove a post I glued.
I prefer epoxy over super glue because, first, it is much better at filling gaps and, second, super glue sometimes dries really fast when it becomes so thin, making exact adjustment of the post orientations while it dries tricky sometimes.
