Just my opinion, but if you speak, make sure not to get bogged down in defining blackhat. There are wide degrees of opinion and you could end up talking about what is and isn’t blackhat for the whole time instead of what you wanted to speak about. (not talking about you in particular, I have just seen too many threads break down into defining it when much more could have been learned)
In my limited knowledge, the biggest BHers use scripts for everything which automates every single step from setting up domains, scraping, page generation, blog and pinging, etc. They don’t always get indexed fast, but they don’t care. Launch a million pages today, get a few indexed from the ones they launched a week or month ago, repeat every day.
