(Edit: I don't know if it would be possible to have a similar site but upgrade direct game log data instead of taking it through a parser. But yeah, as already pointed out, the parser basically just reads your game battle log.) But having your logs up there does not mean you have been parsing, it just means someone in your group has. During the discussion in the latest parser thread, I checked there were over 110 000 public group parses just for OS1, so there are almost 900 000 player parses just for that fight (of course there are generally multiple parses for one player). If SE was to ban all the people who they'd find there, well, you can imagine what that would do to the playerbase (in fact, they would ban you).
You really need to separate harassment from stating numbers though, those are two very different things.
