Same. People signing up for various services, apparently not understanding that they will never be able to read anything sent to this email address.
I get emails from middle schools, online shopping of course, but also emails for at least a couple Trump supporters (not trying to profile; simply getting Trump campaign's constant barrage of emails demanding more money; nothing from Joe's side yet)
What I find particularly annoying is when parents use this account to register for a kid's school alerts. All sort of important stuff like "Do not send your kid to school this week!" or "Where did your kid go?" and because the school itself is also not super savvy, there is nowhere for me to send a reply saying "You need to fix this!"
