Mozenda - do we need a regulator to keep up ethics if data acquisition becomes to easy?

Mozenda, founded in 2007, set out to give non-programmers the ability to quickly and easily extract information from the web.  Today the web data gathering (a.k.a web data extraction, screen scraping, web crawling, web harvesting, etc.), data management, and data publishing is available.  

Dilemma - if it is too easy and allows anyone to do it, how does the market keep up ethics?  Should mozenda and others support a regulator or set strict guide lines on who can use the service?
