This is just my opinion, but I think, especially when new people come here and post about a problem, they are frantically searching for answers. They are probably doing lots of internet searching and may even forget they came here once the problem is resolved. I'm not saying its right, just that I can see how it happens.
I joined a pond forum once when my fish were leaping out and committing suicide. Mostly I read, but I did post my question. About 6 people responded, I found a link to a homemade filtering/no chemical process which I printed and copied. Our fish and pond have been healthy for years. Of course, by the time I realized it had worked and gone to find the forum, I couldn't find it anymore.
I hadn't thought to save it in my bookmarks, and couldn't remember the name. After a bit, I gave up. Since I wasn't an active, regular participant on the site, I, honestly, had forgotten what it was called. I like to think no one lost sleep worrying about my fish.
