I don't block any accounts until they follow the site rules. Failure of authroization can depend on provider of your google account. It can block logging in to Grid Paint. I've met already such situation.
It can be corresponded with that fact that Grid Paint has changed it's geographical location or has changed machanism of authorization in Google (now it's more modern than before).
