Why did I get a low sucess rate creating accounts using a catchall domain

Bulk create soundcloud accounts

Some things to keep in mind when using public proxies to mass create soundcloud accounts
What were the quality of your public proxies?
Usually with public proxies, a high % will just not be working.

Add to this, soundcloud maintains a blacklist which will reduce the working number.

Were all your proxies fully anonymous or did they leak your IP through a header X-forward-by is the usual culprit. A leaked IP gives soundcloud the ability to tie your accounts together by this footprint

Trying to create a 1000 accounts with a catchall all in one go is not a good idea. Soundcloud *may* me able to notice so many accounts being create in a such a short time with an unknown domain. By unknown, having 1000 accounts signup with gmail / hotmail / yahoo is normal, but using your domain, this is a footprint that can be detected and mass blocked / banned.

It isn't as easy as it was to create accounts on Soundcloud. Hence why most promotion packages have stopped offering this or are charging more (or just failing to deliver)

I would recommend you go slower and steadier if you want so many accounts.
