I need help with blackhat seo

Hi there im a uni student looking to open a online perfume shop in the UK. It will list about 1000-2000 products. Im looking for somebody to do the blackhat seo in about a months time. I understand all the complications with google and how it will get blacklisted.
My question is if i launch a ecommerce under one domain name (white hat seo) and then duplicating this website to another domain but carry out black hat seo will my 1st domain be affected when google do a crawl as well as the one which will have blackhat seo.

Thanks.

Panda algorithm will kick in as soon as google bots crawl both sites and your domain will be penalized for duplicate content. I can't say which one, but it'll be either the main domain or both. Targeting different country visitors with different tld but with the same name is a completely different story. Since you're new to this forum and are aware of the penalty, I'd suggest you to checkout some high PR/DA/PA backlink services in the marketplace and keep buying them from different providers until your domain hits the top spot. If it brings some good ROI, you can keep repeating them with new domains. You should also build an email list of the visitors as well as your existing clients who ordered through your site and market to them when you're working on your new site.
