Contributors please be warned.

I canceled my Crestock account and they emailed me they would pay my balance.  After nearly a year they don't respond to my many emails and have gone conveniently silent.  I emailed them with a different email address requesting information for a new contributor which they replied to quickly.

Crestock are criminals.  They've earned money from my content but won't pay out.

all you can do is hire a lawyer and sue them.its gonna cost you but there is nothing else you can do.unfo when you are working with smaller agencies its always a risk.
