I agree, I believe Pinpins is playing a nice little scam.  First this pool was earning much much faster previously before Pinpins decided to up the Sunday Payout level.  Coincidence?  I doubt it.  So now after people mined to that level, instead of paying the .0005 or .001 he ups it again.   Supposedly now it is .0025 and the pool is earning much much slower so I'm debating if its even worth continuing.  Might as well donate my 15 bucks or so to Pinpins because apparently he really needs it badly.  I don't even think its worth trying to get to the supposed .0025 level as I'm losing profits daily trying.    When using a multialgo scrypt with only zpool and zergpool and Zpool keeps winning day after day when its the least profitable pool, you know some weird crap is going on.
