I used Uber eats once, because I got some free delivery, or something, and a friend got a credit for me using it and I never used it again. I went looking for some groceries that skip or instacart could not get me so I signed up for uber again did not find what I was looking for but man the spam just came tumbling in, the host I use has a wild card email so I was able to just create a new email account and for uber. And now all that email just gets bounced with a 550 error, or whatever error it is that emails send hopefully there system catches that and stops trying to send stuff.
