It’s becomes worse than useless when it polls email so often that Google locks your account for one to 24 hours. When I think about, it’s not a lot diferent than another tab in my browser and that doesn’t get my email account locked. Here’s what Google says (without warning) Sorry.
"To keep our systems healthy, Google has temporarily disabled your account. This primarily occurs when we detect unusually high levels of activity on your account. In most cases, it should take one hour to regain access. In rare cases, it can take up to 24 hours for access to be reinstated.
We’re sorry for the inconvenience.
Here are some reasons why this could have happened:
Receiving, deleting, or downloading large amounts of mail via POP or IMAP in a short period of time.
Sending a large number of messages to many people.
Being logged into or synchronizing Gmail on many computers, clients, or mobile devices.”
(a laptop, a desktop and a phone are too many devices apparently)
