I'd like to warn people who consider using your services:
...
No offense genl, I know you really need the user credentials in order to remove the DRMs.
Sure.
If anything, i suspect anyone who needs my help, to understand the risks.
I know how those shops work - they won't simply give out credit card infos to anyone who has login/pass. Perhaps the most important thing users should care about is their password, though. Never give out any password that you use anywhere else. Also, some shops have guest buying mode, which is only generating a temporary orderId/pass pair, thus very share-friendly.
