If you want the real answer Mare more or less had the same functionality and sniffed the same files that Playerscope did, the stalking plugin that revealed alts.
You know, the one Square Enix got screeched bloody murder for not taking down faster, the one they eventually did take down? The one that got a Cease and Desist?

I'm truly not surpirsed that SE didn't bother to look into the "good plugins" and "bad plugins". To them they saw two plugins that sniffed game files that they didnt like, that the community didn't like.

I imagine someone will just make another one that doesn't interact with this data anyway.
