I wonder if the guy lives in a neighborhood with a homeowners association. Those people are god-tier dicks. Getting a house condemned for kindercrap? Yeah I don't think so. Not sticking up for the guy, but sounds like the kind of passive-aggressive horse shit an HOA would pull and "eyesore" is one of their favorite words to throw at people.
On one hand, the yard probably looks like the aftermath of a hurricane rather than "a couple play structures" like Duh claims and I don't blame people for finding it unattractive if the rest of the neighborhood looks more put together. On the other hand, if the guy owns the property, it's his to shit all over as he pleases, even if it looks awful.
I'd wager the neighbors just don't want an awtard flapping around, so they're going to try to make Duh miserable enough to move, which likely won't happen. Now that this has made news headlines, he'll get sympathy on a national scale rather than just a local one.
