From the “I mentioned it once, I kinda have to follow through” department (I need to have a tag for that):

I believed that I would be able to manage the outcome by trying to make a positive outcome for the buyer, for my friends and followers. Even if it wasn’t a good fit, I (believed) I could work with them. But after I heard that they were all just spam marketers, that just kind of killed it for me and I didn’t want to risk that.

I can’t decide whether it was all a publicity stunt (but that would be daringly negative publicity) or he seriously didn’t foresee that the only people interested in buying Twitter followers were spammers. I believe he may just be stupid enough — that’s why I don’t watch Rocketboom (even though the second host was so much more bearable than Congdon).
