I saw a link marked [dead] earlier today and decided to click through and check it out. The submitter had a simple post describing where the idea originated and then broke down the development into a nice timeline of events. He threw this little project together in a few hours with his buddy, working through the night. That sounds like it would be something HN members would support.
At this point, I wasn't sure why it was marked dead, so I visited the site and found some pretty disgusting submissions from what I can only assume are HN members. Comments along the lines of "keep this crappy site off HN" and one submission even telling him to die. These submissions have since been removed.
In any case, the response from HN made me angry and I've been thinking about it all afternoon. Who cares if it's not the prettiest site, or if it's not something you'll ever use. This guy built his project and shared his experience with us. The least we could do is give him some constructive feedback so he can improve it and maybe learn a thing or two.
Here's the link to his original post: http://news.ycombinator.com/item?id=1800925
What happened there is no different than what happens when someone posts a spreadsheet with useful stuff here. Within minutes it will get destroyed or defaced.
The 'griefers' have definitely discovered HN. I suspect that some of them are people that took rejection by YC a bit harder than they should have, and that some others are simply here because they can't see a good thing without being tempted to try to destroy it.
Anything - and I really mean anything - that you put out there on the internet needs to be designed with abuse in mind, because no matter how small it is the abusers will seek it out and will try to destroy it.
That's something that you need to be aware of as much as you need to be a coder or a designer when you plan on making a living online.
Better get used to it.
