Same exact issue. Especially with people from Africa for some reason. I get a lot of stuff from 3 people from Kenya, Zimbabwe, and South Africa. Most everything there is managed by phone, and they just use my email as a throw-away address. The guy in South Africa has a collections agency after him. The guy in Kenya likes to order food delivery quite a bit. I occasionally change his order to extra spicy. The guy in Zimbabwe works for a college of some sort. I make sure he's signed up for all the educational trips to Europe.
Also some senior woman in Oregon, who is a frequenter of "silver singles".
Some industrial supply company in Canada is very confused by the fake Groupon I sent them for the free stuff they are trying to bill me for.
Some guy in Australia has his security deposit box setup with my address, and is way overdue on some payments.
(I've tried multiple times to correct the wrong email address of the people I mess with, and have been ignored)
Lots of US political junk mail, from many localities, both parties. LOTS AND LOTS OF KINKY PORN SITES.
Fortunately none of them have the dot in the address and I have a filter to send them all directly to trash.
