Old thread, I know, but I don’t think it at all ridiculous that you can’t delete a design dilemma’s entire thread once people have engaged with it. There are numerous people on here who spend countless hours and a lot of energy helping with dilemmas, even looking up or creating pictures to illustrate their points. Wiping out all that effort would be ridiculous and discouraging. Just as ridiculous as when Amazon deleted all those discussions in the comments on reviews —thousands of hours of collective effort and knowledge (I haven’t written a review on Amazon since). As for Reddit, I love it too, but there are countless times I’ve come across a thread in which the original poster has deleted their post, leaving it a mystery what all the responses are actually addressing. Very annoying.

I doubt it is true that the post can not be removed. I can not COUNT the number of times a poster gets offended by a few replies, a thread takes a bit of a veer, and magically when one gets curious and checks history? You get..........

"The page you requested no longer exists"........or something to that effect.

The age of the comment or post matters. Both can be deleted/ammended with in a certain time line but after that the posters option for this are gone. I don't know the time line but I have noticed one exists.
