You mean like Fluttershy1909090? (just using something random) And they have a pic of Fluttershy? Perhaps it is their favorite character, or perhaps she expresses how they are, a bit timid and shy. Or perhaps they just really liked the particular pic. Like mine, I have no idea about it. I just know it is a gamer girl called Vivian James and has something to do with 8chan/4chan and that is it. But I still really like the gif. 

Some people don't necessarily want to be particularly identified. Some people would rather just blend it than be in the spotlight. 

Not quite, that example has numbers at the end, (quite a lot actually) that makes all the difference and it is more than enough to say "in not them". If it was just "fluttershy" with a picture of fluttershy, that's what I'm talking about, and I have seen it with every show pony imaginable on this forum, I even saw someone as daybreaker only hours after a royal problem was released and that's what lead me to ask why. 

Oh, I see
