Without making it personal, I don't have an issue with the bidbot model.
What I do take an issue with is their complete and utter lack of responsibility when it comes to bad content. I'm not even going to use the word quality.
They will not hold themselves and their customers accountable and thus have had a great negative impact. Had they acted like responsible businesses it wouldn't have been that big of a deal.
I've defended the model many times, but not the current owners.
