Bill I'll have to admit I don't know exactly what the mod validation process is. I do know the guidelines set down are pretty strict to help prevent exploits from creeping in to begin with. It's my understanding the ones that do get rejected are usually because they don't follow the guidelines. There's a team of about 8 mod validators and only about 150 have been validated since about this time last year. They just added some "junior validators" to pre screen mods to help speed up the process.
