The easiest way to circumvent the DF problem of people getting kicked from the official parser would be to only show the breakdown of the parse results after a dungeon/raid is cleared. Simple. People can simply leave at the end before they harassed for their extremely sub-par dps (E.g. 700 and below dps at i190).

This wouldn't solve the initial problems of people getting kicked from DF by people using the unofficial parsers still. The way to solve this problem? As Yoshida once said, "Git Gud".
