Stop automatically entering me in high score fantasy basketball leagues through pop up advertisments
Its incredibly annoying and scummy that the button to close the add is right next to a button which just automatically enters you into a draft that you cant leave. This takes up one of my available leagues for something i don't care about and never wanted to enter.

The league that you signed up for is referred to as an "Instant Draft." This means that you're automatically placed in a Public league once you enter the draft lobby. Once the draft is over, it's not possible for you or Yahoo to remove or transfer your team from the league. It sounds like you accidentally joined this league without realizing. Yahoo will not place you into a league without you doing it. You may have clicked on a banner at the bottom of the app that will show that says "Draft Now".
We apologize that we can't be of more assistance, but do know that you're not obligated to visit the team pages for the entirety of the season. You can disable email notifications (https://help.yahoo.com/kb/edit-yahoo-fantasy-team-yahoo-account-info-sln6128.html) for your team if you'd like. In the Yahoo Fantasy app, you can either hide your league from the home screen if you are using an iOS device or customize league notifications using the steps below.
Hide your teams:
-Tap the Profile icon at the top left.
-Tap Settings.
-Tap Customize menu.
-Tap Hide next to any league you want to remove from the home screen.
Customize notifications:
-Tap the Profile icon at the top left.
-Tap Settings.
-Tap Push Notification Settings.
-Tap the league you want to customize notifications for.
