What is ‘persistent opt-out’?
I am not sure what you are opting out of.
Various controls and settings are listed under the settings icon — between your Hi, Yourname and the house icon.
Yahoo “pushes” ad spam to you - especially now that it is forcing users to switch to the new Yahoo mail.
The default when you switch is “opt-in”. It can be disabled [which I have done], but it only works for the computer that you are using at the time.
If you go to another computer, “opt-in” is automatically enabled - unless you disable it again. But, if you go to a 3rd computer - it is enabled all over again.
There is supposed to be a “persistent opt-out” function in the account e-mail settings from Yahoo that creates a permanent “opt-out” for ALL computers. So, I would NOT havee to keep disabling the function ...
BTW: The “pushed” ad spam from Yahoo is created by Yahoo reading the content of ALL of your e-mails, IMs, etc. Then, Yahoo sends you spam e-mail based on the content that it read.
Yahoo getz bucks from advertisers for this ...
