Account block when first login

Hi I bought the Aged Twitter account, and after I login it by the proxy on the MP, it said: the account is block.

Can I use the proxy to login other accounts in future?

Is your account disabled or they just ask you for verification/password reset?

Not suspension.
it said : the account is block

Unblock it then, through embedded browser. And feel free to use 2 more accounts on that proxy.
