Damn that's awful, hope you're able to get the people sending threats reported/banned at the least. Just stopping with the release dates and dropping it when it's done is probably the right thing to do, frankly I'm kind of amazed you feel the need extra remixes as an apology; remember that you don't really owe anyone here anything, and the only thing you owe your actual paying customers is whatever you've promised on Patreon. Good luck.
