This is an update to my previous post. Tl;dr for that post, for everyone why didn't read it: Soundcloud had taken down my account without telling me or giving me a reason.

I messaged them and asked what had happened. They just replied, saying my account had been accidentally taken down as spam. They've recovered my account, thankfully.

I don't know what triggered the bot that flagged me, but at least it's back up, so I guess things are fine now.

That's it. Make sure to wash your hands.
