They are a low seller, al least for me compared to Pond5 or Adobe but they do have some sales. I do submit only from time to time as their weord hard rejects get on my nerves, no explanations by inspectors whatsoever. They are very low on my list and I have a fraction of the content I have on the other sites. Stocksubmitter makes it easy to submit to them. If it wasn't because of this I would no send a single file to them because it is not worth the effort. But with stock submitter is only a few clicks.
