Yahoo is not "...at odds with Crowdstack...." Yahoo does this to hundreds of domains that they think are suspicious or are spammers. That's why Crowdstack Tech Support said, "...it is just Yahoo being Yahoo..." They are "protecting" you.
Yahoo has become typical "Big Tech", just like Google, Twitter and Faceplant.
