Google suspended my account and purged all apps on April 7 due to violated content policy(?). Not knowing what indeed does it mean because Market Enabler is still there now. I appealed resuting in no response, and they even suspened newly created accounts.

Update on May 10th – Google removed Market Unlocker Free and Pro again. I will not publish any more. Please download apps from my site and upgrade using paypal if like.

And as I know, google removed similar apps as well, like Market Enabler.
