Asking Joe Bloggs the armchair investigator to look at satellite imagery is about as useful as asking your pet dog to go shopping for you. Tomnod and other crowd sourcing MH370 endeavours have proven this beyond doubt with their 100% false positive ratio.
In other words, the "crowd" has done just as well as the "experts" with their fancy government satellites and the SAR guys doing visual searches via planes. Everybody has come up with false positives - at least partly because they were searching in the wrong areas to begin with.
