Parsing's fine.

It's a useful tool to utilize to improve. It's a necessary tool to help diagnose problem areas in groups (re: Statics). Report people who harass you with it, since SE will take action.

If you're upset people can see you're not a good player, who cares. Don't party with people who don't want you, and who you don't want.

It's not private information, SE owns the account you're renting. Which means the character data is SE's data. If you're still scared about your numbers being posted to a third party website for something as trivial as a videogame, go and hide it. Or just stop doing content people parse in.

Yoshida is fine with it, a tool providing direct information to the player that can then be critiqued is healthy. No one can get better if everyone's blindfolded.
