Well, here's another reason not to go exclusive
(not that anyone is seriously considering going exclusive with Crestock)
but I think it strongly demonstrates the danger of relying on any one agency.
Basically I have been unable to upload since December, and, despite numerous attempts through different channels, Crestock support apparently doesn't seem to care much.
Fortunately, Crestock represents a very small portion of my earnings, and I am definitely glad I don't depend on them for anything.
