I agree with SnF, it's all about balance of tastes; they should compliment each other without one overpowering the others. In this case, salt has decided to kick ass.
Since its already been heated, the LAB are dead. So, adding more ingredient(s) and continuing the ferment is not really an option. Also, I don't think there's an effective way to remove the salt. Some say to do the potato thing, some say it's a myth. Your experience says myth, so I'll go with that lol.
One thing you could do is can it and use it as a base in future kitchen endeavors, a la AJ's Puree.
Or, try to bring the salty flavor back in balance with the other flavors. You can do this by diluting (increasing overall volume) and/or by increasing other flavors. To increase volume, just add more fruits, veggies, etc. To "cover up" the saltiness, add acid (lemon, vinegar, zest, tomatoes, etc) or sweet (fruit, carrots, honey, sugar, etc). Or, any combination. Of course, the more you add, the further away you might get from classic fermented peppers and into more of a blended, balanced product. Personally, that's the place I like to be.

Good luck with it. Let us know what you do.
