I think that the whole building as a way to get unbanned is extremely annoying and I don't think it should be an option at all. Unfortunately that concept seems to be final. But I do have a suggestion to make it so that if someone is building a route as punishment, that does not limit real builders from participating in the construction of that part of a region. How about if someone gets a route assigned as a punishment, then they have to finish that route But if some other official builder desides to build it, then the punished one can either start and finish it before that person gets there, or ask for a new route to build. Another cleaner/simpler way would be to have the the punished player build the route on a seperate area of the map and then once judged, that route would be pasted in OR if a real builder wants to build that route themselves, then the punish route is deleted.
Just a suggestion, because I'm seeing more and more "you cant build here cuz its my punishment"
or in tenes words:
if said banned person hasn't finished their area by the time you're ready to build it, bad luck for them and they get assigned a different area to build.
