Some communities don't think pages belong to anyone. That include userpages. Well, at least on Wikipedia, which is where much of the MediaWiki software was developed around. Your best bet would be to ask a local administrator to protect your userpage from editing (Just make sure they set the correct protection level so they don't lock you out as well!)
