Pvp usage and potential abuse?

i was wondering if there is anyway to prevent abuse, ive used this plugin on a semi pvp server and discovered that if someone raids a base and replaces tc and then repairs and re-purposes the base that the original owner can come back and simply remove walls regardless of there being a new tc.

any thoughts on what can be done here?

"Use Entity Owners": false,
"Use Tool Cupboards (Strongly unrecommended)": true,

Using that config only allows tc authorised players to remove/add to base
