As mentioned in this issue https://github.com/MLG-Fortress/PopulationDensity/issues/106 the sigs can be edited by any player and they are not protected anymore. Although it is not very critical because the signs are regenerated every while and then. I think it is better to fix it.
I only added an extra event handler similar to the one used in onBlockBreak to protect a regionpost.
Tested on local paper-1.20.1-32.jar Server with op User and normal User
