I found this also this earlier this morning but was too tired to say anything.
This was the answer during the Yahoo 72 hour ban that Yahoo was giving several members and I remember that. Yahoo changed some of there banning rules due to increased BOT activities, etc..
The most recent problem is the pop ups and now if you click the wrong button to refresh your lobby page without going completely out and back in, your ban would go from 72 hours, to one week, to one year, and as mine went--until 2020.
We are looking into this so hang tight.
