#SoundCloud updated its Terms of Service, apparently in Feburary,
https://uk.news.yahoo.com/soundcloud-quietly-updated-terms-let-155655189.html
Basically, unless you have a record label or other third party rights holder managing your SoundCloud, this line in the ToS applies:
"You explicitly agree that your Content may be used to inform, train, develop or serve as input to artificial intelligence or machine intelligence technologies or services as part of and for providing the services."

They've doubtless already scraped my work, but they don't deserve to keep it if they pull T&C changes like this.
I'll be taking my stuff off there and hosting Faircamp, I reckon. Maybe dump the actually popular stuff over to Bandcamp for discovery purposes? (But is that just asking for this to happen again.)
