With regards to SoundCloud's future, their revenue is growing, they're profitable, and they've recently raised. I'm also one of the developers working on it. Can't speak to fraud as it's not my area + NDA, but earnestly, thank you for reporting what you see.
Interesting! Sounds like the company is doing pretty well, that's nice to hear. I'm a fan of it, just wish there were fewer bots. Thanks for your work, whatever you're doing there :)
