I just created 2 accounts, one with vpn and one with a public proxy so I don't think this is a good deal. To add funds you can use Steam Gift Cards (with ARS currency), ask sb from argentina or just trade items. It's true that many vpn services are blocked but.. I mean if a public proxy works, why not going the easy way?
Also you can't gift games to other accounts and you can also get banned at any time due to the steam ToS
