Post an AdobeRGB or wide gamut colour space image, and these will be interpreted as sRGB and will look rather "muddy". This really doesn't matter to most viewers as most of the computer screens out there are not capable of reproducing more than basic RGB anyway.
And anyone who posts a monochrome image is throwing away even more data, as in B&W image, as all channels are set to the same value (R, G and B), so really you are effectively throwing away two of the three channels of data.
