There's statistics for most submitted/added bands, albums, artist by the user. Just out of curiosity, is there statistics for most most rejected/black-listed only by genre bands for users? I've got at least 61 at the moment.

Nah, sorry.

I have listed all the bands I submitted that faced rejected on my profile. Some have found their way on here and I do use it double-check any new releases that may get them on.

Well, there is a history of deletions and rejections, but not a "top users" list per se for that. Not something to celebrate, really. I think once a user sets a rejection back to draft status it disappears from that list, though, regardless of whether it got rejected previously.

That list is mod-only, of course, but it does have its uses; ex. restoring bands and I know at least one moderator who sometimes goes through it in search of bands that may have a valid release after all.
