Lol!
From your link...
"The prestigious European Space Agency has declared Phobos, the mysterious Martian moon, to be artificial. At least one-third of it is hollow and it’s origin is not natural, but alien in nature. The ESA is Europe’s counterpart to NASA. Could this revelation motivate NASA to release the secrets it’s harboring? Don’t count on it..."
“Phobos’s density is too low to be solid rock, and it is known to have significant porosity.[12][13][14] These results led to the suggestion that Phobos might contain a substantial reservoir of ice. Spectral observations indicate that the surface regolith layer lacks hydration,[15][16] but ice below the regolith is not ruled out.[17][18]”
