During 4 years on Stackoverflow I've noticed that over time I got far less answers to questions and instead more and more comments like "this shouldn't be here" or no answers at all. Now being compliant with the regulations has become far more important than helping people with their problems.
There's a huge class of problems that is known to be unsolvable by a simple code snippet so suggesting a library is the only possible answer. There are thousands of questions like this on SO. In such a case what is the difference in asking for a 'solution' or asking for a library?
Many questions like this have been closed even though they get lots of upvotes - which means this is something people want ask and get answer for.
An example is question from today: https://stackoverflow.com/questions/21028484/how-to-upload-file-to-string?noredirect=1
