why is it that everytime i donate to someone in gratitude for their free service that they provide, they eventually become assholes and stab me in the back? You'd think that maybe, admins would have less patience when people are being freeloaders, but in my case, it's like "Oh, I've milked you for cash, now I don't have to be nice to you anymore." Maybe from now on I'll ONLY use my money out of self interest.
