Finite Space for Merch Sellers.

Do you think it's possible, that until the new Merch facility gets built that Amazon has in their head a threshold of how many people that they want in? And as members accounts get terminated for various reason such as inactivity or too many violations that they cherry pick out people who will be more successful because they added website in the optional field, that shows either some degree of graphic design, using other POD services, or even their own epublishing part of Amazon?

Or is this my own conspiracy theory and it's still random and all luck based?!
