I canceled my Crestock account and had them delete my images. I site their severly inconsistent reviewers, and lack of return on images sold.
While they maintain that they "only accept images of the highest quality" I have found that they reject images that were accepted by dreamstime, and accepted images that were rejected by dreamstime (they did not know I have images on dreamstime). They accepted some of my (really bad) first attempts at Stock Photography. Then there is the paultry return on a sold image. Most images I sold returned only $0.25 and on very rare occasions I would get $1.00.
I am not the only one who has had the same problems. Their forums are full of similar complaints. With some "professional Photographers" having had whole batches of submissions rejected (200 to 400 images) because one or two pictures in the batch did not meet their standards.
Maybe some day I will try using them again, but not until they get their act together.
They did not remit my $7.50 for the images they sold.
