The limits for rejection

We’ve currently seen a huge variation when it comes to what the reviewers pass along and what they reject and have some question regarding that:

  1. How much reverb can a sound effect have before being rejected?
  2. How high noise level can a sound effect have before being rejected?
  3. When is a sound effect too hard compressed?
  4. How long can a fade in and out be?
  5. Can a submission be rejected because the keyword in the description or title are the same?

Thanks in advance for all answers.
