The OSVDB went pay a few years ago. They have a wealth of interesting information and use to be fully open source however due to lack of community involvement they decided that the open source model wasn't working for them.
If the OSVDB has a problem with people scraping their site, they should really update (or in their case - create) their robots.txt. I was interested in this data myself a year or so ago until I found out they wanted me to pay a subscription to access information I can view for free on their website and screen scrape for free if I really wanted to. Further more, I noticed that google has completely cached their site because they take no preventative measures against it. If anyone wanted this data, they could easily screen scrape it from the google cache and the OSVDB would be none the wiser.
Why should anyone pay for data that the OSVDB has literally done nothing to protect?
