I wouldn't take it personally considering the source. I think micro-stock music has little relevance to the rest of the production music industry. It's a bit fixated on "corporate" music, despite the attempt to expand towards the higher level broadcast market. While other styles sell in micro-stock, it's to a much lesser degree. The customers here aren't very picky and seem to be happy just going to the top seller list over and over again - not because it's any better than the rest, but because their needs are very simple and the top seller list means no searching required.
I'm now retired from royalty free music. I thought about offering old tracks here, but decided it would be a waste of time. I don't compose "corporate" tracks and my style doesn't sell well here. I did a test for about a month or so under a different username and got about 47 sales. One work for hire project for a regular music library generally takes about three weeks to a month and earns at least 10 times those 47 sales. Therefore, it doesn't make sense for me to try and compose new music in a style I don't like for this kind of money when I can just continue to do what I do for more money and enjoy doing it.
So - Why did I remove those old tracks I had here, some may ask? I found out that AJ is a big target for music theft by those who intend to resell it as their own. That's based not only on the numerous forum posts, but what I've see with my own eyes on the internet elsewhere.
