We make some attempts to be human, though dedicated bot checks may well find Donobu. The things that work in Donobu's favor is that it is intended to be run locally, and so requests coming from it do not come from some giant Amazon or Google data center IP address range. Also, Donobu is not optimized for mass web scraping (it has deliberate delays included), so it does not tend to get rate limited. That all being said, there is some low hanging fruit we will be working on in order to be generally less bot-ish.
