Entities limit on Toronto?

Cant build, place anything.

Does anyone know, as structures are removed, due to decay or pick axe raiding. Does this free them up, allowing for more building to be done?

I believe that was one of the reasons decay was added. Players abandoning their raided bases and building somewhere else causes server lag and adds to the “limit” allowed.
