But the minute they begin to scrape too much information I would simply remove it to elsewhere or make it unreliable enough for Google to stop scraping.
The idea that you need to revise your site and move things once Google finds them is like paying to stay in a hotel so someone can rob your house.
I have seen some sites resort to encoding text as a graphic image so it can't be scraped.
but its not going to stop at that, is it.
And I don't want to become an unpaid editor for Google more than I already am.
For one of my sites I spend a lot of time collecting and editing event info. I post events from theatres, bars & nightclubs, museums, schools, churches, non-profit/fundraisers, etc (for a single geographic location). I complete the listings with full address, phone, email, web links, etc -- (e.g.- if a bar has a band playing, their website might just read "The Examples 9pm, Tuesday"... I'll look up "The Examples" and find out what type of band they are, e.g. "Top 40 Classic Rock from the 70s, 80's and 90s".. get ticket/cover price info, etc, etc)..
