Description of offense and evidence (screen shots, logs, etc.):

I am trying to make a base for me and Bengis to bhop in when TheOriginalCZ and UHC keep deleting it, they say that I'm building in their base when I'm clearly not.  They think they can take the entire map as their base and prevent people from building but they can't.
