Im curious, Are you also getting blank audio files?
My personal opinion is that text feedback would better for a development team to understand and work on.
If it is to be added to a popular app, you may notice a lot of noise and by noise, I don't mean audio noise :-)
The only thing I can think of maybe is that after submission, the results could be shown to you.
Also, was there any significant reduction in the spam posts after installing reCaptcha?
