I am not aware of how widespread this issue is, because it's not something I've really experienced personally. But if it is a problem, wouldn't it be better for SE to issue a statement against the use of this site for harassing other players? And announce that their GM's will take complaints in this regard seriously? There is already a "report for harassment" option. Go after the players doing the harassing, rather than the tool they're using to harass them. Because people will still be able to harass you without the tools, they other means of finding out if your DPS is not meeting their standards. They may point to your iLevel, they may observe your rotations, they may well be the other DPS and decided that they're not the problem, so it must be you. It doesn't take much to read how another player is doing, as one who tends to main healer, if it looks like the healing is down when I'm not a healer or I have a co-healer, I'll observe them and if they seem to need help, then I can offer help.
