If you're doing scraping for some purpose other than spamming or stealing somebody else's data, I have no problem with it. In my experience, however, the majority of cases where somebody scrapes web sites for hire involve email addresses to be used for spamming. That doesn't mean that there aren't legitimate uses for scraping, just that I don't often see them in use.
During the past few years, I sold a couple of data scraping solutions, none of which fitting into your less than legitimate categories. So, if you are seeing mostly illegitimate uses of scraping, maybe you want to look for another peer group of people to work with?More importantly: rather than insulting people enriching the bitcoin economy by providing services, why not offer services yourself? Just an idea... :-)
