I run a niche directory so your site either fits the niche or not so I find no further rejection information necessary.

Example: "We only accept sites of widget makers and your site is not about making widgets".

Additionally, charging a nominal non-refundable submission fee cuts out all the junk.

It stops all automated submissions dead in their tracks when it requires paying with a CC to complete the process.

Another simple junk control method for free submissions is email verification of the submitter to activate a submission. This pretty much puts the stop to most, if not all, automated submission programs that target your site.
