You were automating it, weren't you?

With bookkeepers, accountants, etc. the login and work done on the system was manual. It was an actual person doing it.

In your case, a computer is doing it instead.

Virtually every site out there, from Facebook to Twitter, prohibits the use of bots and scraping. Not surprising ADP isn't a fan.

What is surprising is that you feel you're entitled to access their system however you want? It's their system. If they want to prohibit bots and allow only people, that's their biz. If you think ADP is full of it, create your own system with a public API and put them out of business.
