volunteer and get reprimanded

A Canadian pensioner built a set of stairs at his local park for just C$550 when the city estimated it would cost at least C$65,000 ($51,500, £40,000).
But instead of a thank you, Toronto has blocked off access to the steps and asked Adi Astl, 73, to take them down.

Looks like a pretty sturdy set of stairs to me. I guess the whole matter needs to be filed under "no good deed goes unpunished."
