Scraping of a marketplace with high captcha rate

There are three markets that are only accessible through the Tor network. All three show a captcha about every 10 pages, and there are about 70,000 pages to download on each. In one case, instead of a captcha, the account that is used to scrape is banned, and a new one needs to be created. The captchas are not standard and are quite complex to solve. There are no emails in the registration form making account creation much easier.

I need to collect all of the data from all three markets.
