Yes. I have never seen this much in the neighborhood. Go ahead and report the other six. I have been reporting them as I see them. The mobile app works well. The 2418 situation was settled - no more mattress.

There are plenty of laws and regulations that should be applied to these pig sty messes:

Improper storage of solid waste (21 DCMR 700.3) $1000 fine
Failure to containerize (21 DCMR 703.2) $150
Open food waste stored (21 DCMR 704.2) $500
Unenclosed solid waste collection (21 DCMR 70S.4) $300
Nuisance or unsightly (21 DCMR 806.10) $150
Littering (21 DCMR 700.4) $75
Illegal Dumping (24 DCMR 1000.1 ) $1000

I assume that the police can issue tickets for breaking these regulations.
