I noticed a slightly dubious looking profile calling itself a repost network. There was a link on the page which went directly to a PayPal account asking for $7, but it also says in the profile description:
"After the payment your track/ mix or set will be reposted within 24 hours on all partner channels."
This has got to be against SoundCloud's terms and conditions.
I then did a search for the link and their profile text and found a load of other accounts all with the same link to the same PayPal account.
