It makes sense that you can't use Google to sell guns or booze but now they're expanding that ban to include the sale of essay writing services. It turns out that over 12,000 essays have been sold online in the past year (and those are the ones on record). In an attempt to stem the tide of cheating, Google is now banning the advertising essay writing services.
Implications - The ban will start as of June 2007 and will surely be a relief to many teachers. A high amount of university professors have complained to Google that students who purchase these essays should technically not be eligible to get their degrees, since it wasn't the students' work.
