The contest holder has a few ways of providing feedback - they can give ratings (which we also call Instant Feedback), they can provide private messages back on your individual entries, as well as public messages to the entire community. Contest holders are encouraged to use all those features to collaborate with the creative community.
However, the Contest Holders are not required to use those features. At no time should you expect to hear back on all of your entries from ratings to specific feedback.
It’s also important to note that per our Terms of Service, you are not allowed to follow up on names, request specific feedback, or request that your names are rated. You can submit names and leave detailed comments, but is at the discretion of the contest holder that they’ll reply to any names or your names in particular.
