 I replaced this: 
 Where critics accuse hoax proponents of unscientific or unfalsifiable beliefs, hoax proponents have sought to demonstrate that experiments could be designed to test their theory, for example, by making observations of the landing sites. This would require the diversion of astronomical resources to a task of uncertain scientific value. It is also unclear as to why this would be considered convincing evidence when other material items of evidence are not. There is little reason to believe that hoax believers would be convinced by images taken of a landing site. At scope resolutions soon to be available, only outlines of landers might be glimpsed, leaving the possibility that these, like the retroreflectors mentioned below, are robot spoofs; if a revolutionary telescope was in the future able to resolve footprints, etc, its print-outs could easily be dismissed as more NASA 'fakery'. 
 with this: 
 In response to criticism that the hoax theory is unscientific or unfalsifiable, hoax proponents have designed experiments that could be used to test their theory, for example, by making observations of the landing sites. The main reason that these experiments have not been carried out seem to be the the accusations are not taken seriously, and a scepticism that hoax believers would be convinced by further evidence gathered that could also be falsified. 
 It's more factually correct, shorter, and reads better.
