yahoo sucks, they require your mobile phone with SMS verification to make a March Madness bracket. Doing this also means you automatically opt-in to receiving all their marketing SMS messages.
From their KB (https://help.yahoo.com/kb/tourney-pickem/sln22954.html)
- Your consent to receive up to 2 automated marketing text messages per week from Yahoo.
- Your agreement to use electronic records to document your consent to receive text messages.
To opt-out you can reply STOP at any time or manually fill out a form. Yes, you can manually type out you want. Here’s their own instructions again from their KB (https://help.yahoo.com/kb/tourney-pickem/sln22954.html)
In the Detailed Description field:
Mention the particular product (Tourney Pick’em, Billion Dollar Bracket Challenge).
Say you want to stop receiving SMS/text messages and notifications.
Include the phone number that messages should stop going to.
The form also asks for your birth date, your secret question and answer — all as required fields. No fear though, hidden in their help, it’s perfectly acceptable to just enter ‘unknown.’
no thanks, yahoo sucks
