Yep, we've had exactly this issue with the web portal on one of our applications. A customer used some 'quick and dirty' convenience tool that used web scraping to invoke the portal application pages, and wrapped that up with part of their admin workflow. When the pages changed, even slightly, it broke their admin tool. We had said not to do this, but the workflow/web-scraping tool was surely quicker and cheaper to implement than custom API development within that organisation.
