Increased number of rejected submissions

Has anyone else noticed that Pond5 has apparently become more strict about what they allow to be uploaded and sold? I have music that I uploaded years ago that is not nearly as high-quality as what I can do now, but I've recently had tracks rejected. In the past, this never happened, even if I thought the track wasn't that great. I understand if they want to "clean up" the library and only have higher quality stuff, but I still sell a lot of that old stuff that isn't as high quality, and Pond5 is still making money off of those songs.

One of the times something was rejected, I actually responded and expressed my confusion. The curator wrote back and said upon further review, he would approve the track. Do they just have so many submissions now they don't take time to really review a song before rejecting it? I'm pretty disappointed in what Pond5 seems to have become. I feel like it used to be a place where people could get there work out there and make some money off of it even if they weren't accomplished musicians. Now I feel like that's pretty much gone.
