You overstep yourself.

If the best you have to say of your own work is "nothing i(sic) put much effort into," then you should not expect any more regard from your audience. You do not have the right to tell us what kind of comments we get to post. You waived that when you posted that to a public forum like Newgrounds and now you get to hear it straight.

So yes, as you say. Nothing you put much effort into. Try that, before you even think of submitting anything more.
