I am online at SL now since the beginning of March 2009 and it's funny to see how by even entering this virtual world the power of blood can't be resisted. Yes I write in rl too but with one difference. In rl I make money with it :p And no, English isn't my native language but being in SL is a great way to improve that.
I come and go in SL and will write here only about my experiences in SL.
This picture shows u a clear example of MJS and it only occurs with women wearing prim feet. The depigmentation of the skin can be caused by a number of local and systemic conditions. The pigment loss can be partial, complete, temporary and permanent. In case of the MJS it's a partial and permanent pigment loss in their feet due to lack of color sense. These women have whatsoever no idea how to match the color of their feet with their skin. The lack of color sense is often also shown by the clothes they wear. They wear the weirdest combinations and colors just don't quite fit together.
You could ask yourself: Is this a male operating a female av or just a woman with poor taste?
P.S.: An example of complete and permanent depigmentation is called albinism. Heino is a good example of that.
