It’s winred. They suck. I gave money to Pres Trump and of course the first time I did I was unaware of the pre-checked box because I didn’t look. My fault btw. So...when I got the email confirmation for a ‘repeat’ contribution, I contacted them immediately and had it canceled. They didn’t get any extra money but it wasn’t not for the lack of trying.
All in all, it sounds like chicken sh!t petty chicanery, not “millions”. A money cherry bomb.
I unchecked that box and it still happened.
