I honestly don't feel this kind of behavior is acceptable from any artist. If you don't want fans to want new music from you or to know when a possible album may be coming out without you going off on them they need to look into some other job. Without these few fans you got left you'd be lucky to even put out another album. Don't be ungrateful. If the music is for you only stop putting it out there. Keep it to yourself. Simple. Don't bite the hands that feed you.
