Players should only come on here if they are the sort that use criticism as a motivation (in that "I'll prove you wrong" kind of way). A) it's (mostly) a fan site, fans are generally less educated about football, what you've been instructed to do, etc B) it's an internet site, which brings with it, people who pretend to be negative to cause trouble/get a reaction, people who aren't at the game and going on second or third hand accounts, people who use anonymity to say with certainty things they would keep to themselves if their name was put to it for fear of embarrassment or ridicule, and gives an instant outlet for people to post with their emotions rather than allowing themselves to calm down and reflect and use their brain.
