Hey Casino1784,
Have you tried a Reinclusion request for your site? Of course a reinclusion will only work if you have removed all your blackhat tricks from the domain.
Just send the request, fess up to the old blackhat ways and let them know that you’ve changed your ways, that you’ll never go back, and that the site is now free and clear of any blackhat tricks. Someone from the Spam team will visit and if they don’t see any blackhat tricks going on they’ll lift the ban on the domain.
I’ve done this a few times now for some pretty big sites and it’s never failed. Google is pretty good about letting domains/sites back into the index that has reformed their ways.
Of course you could always blame that SEO guy you hired a few years back. :wink-wink
If you want some help wording the reinclusion request just PM me and I’ll be happy to help.
