Being dry, of course, makes it easy for dust of the Lunar regolith to retain electrostatic charge, but lacking an atmosphere to intercept the incoming solar wind also means that the surface is constantly bombarded by charged particles. The result is a highly charged environment, which causes the dust to be easily disturbed, and incidentally, to stick to any body that is differentially charged. Note, also, that the low gravity of the Moon not only causes the dust to return more slowly, but also allows it to be kicked up in a higher and wider arc than would be the case in a terrestrial environment. Even a cursory search on “Moon dust” will turn up a number of NASA and academic research papers on the behavior of lunar dust and the hazard it presents to equipment and (potentially) the health of astronauts.
The “it looks weird, therefore it must be fake,” is a standard meme in both Moon landing deniers and other space conspiracy arguments. There was a previous thread on the Chinese manned space launch and how it must have been faked because (based upon a poorly made YouTube.com video narrated by Hugo the Abominable Snowman) the movements of the taikonaut and his support equipment looked “weird” and artificial. As Chronos notes, to any skeptical observer, this should be considered an argument for the positive, as we should expect the mechanics of objects and people in freefall and vacuum to be very different from what we see in terrestrial conditions.
As for “…another piece of evidence in that Moon landings having been faked?”, I’ll have to point out that faking the Moon landings would require a conspiracy involving tens of thousands of engineers, technicians, and scientists to create a technically realistic effort to develop a super heavy launch vehicle and spacecraft. It would have been logistically more difficult to fake a Lunar landing than to actually just go there.
