Not sure if you are suggesting this, but I really want to discourage any "don't draw attention to a problem unless you have a solution" bullshit. These are two separate things, and they both have value. It is nice and good if you happen to have a solution to a problem that you've identified, but to keep silent about a problem just because you don't have a solution is nuts insofar as you would like for the problem to be solved someday.

There are productive ways to filter writing (writer is doing crappy analysis, propagating misinformation on purpose or through incomptence/ignorance, etc), but doing so based on "did you propose a solution" is actively harmful. Remember the "don't jump to solutions, scope out the problem first" bit.
