If they have been "temporary disabled" for a long time, the only way to get someone's attention is to ask for it to be archived. The reviewers apparently don't see the "needs maintenance" requests, only the "should be archived" requests. If you have a spot that you might want to put another cache into and it is being blocked, then perhaps you should request that it "should be archived". Then the reviewer will look at it and try to contact the cache owner. If the owner doesn't respond in a reasonable length of time, the reviewer can archive it and then you could put your cache there.
