Ref redirecting and bad Karma;

There is another way of doing it, I've tried that with fairly good result.

Replace your old site with one single page. On this page, link to many authorities in your field (20-30 or so). Put these links at the bottom of the page, make them same color as background if you wish, you are not bothered by being listed by Google here. In fact you couldn't care less if they ban the site again.

In the upper visible screen area of the page - put one big JPEG picture saying something like:

"Site has moved - read all about exiting new gizmos HERE"

Link the JPEG to your new site.

User sees "Oops, click here to get to the site".
Google sees "link page with lots of stuff, one of them being your new site". Dilutes bad karma. Do it with CSS so the authority links come first in the HTML but last (visibly) to a human user.

Variations: Make it more pictures so many other pictures link to some authority site. Make sure these pictures are very bland, maybe even squares of same color as background. This makes your linked pic stand out less to Google.

Variation no 2 (slight risk): Make this page REALLY black hat. Use everything forbidden, who cares. Add another 50 of these pages, all totally black hat. All linking to a page on your new site but also to a LOT of other stuff. You will get 50-80% click-through from users who arrive via a search engine and probably near 100% from old users accessing the old site directly. Risk is that someone complains to Google who then decides to ban the new site as well.
