It's honestly not surprising that I would get hit with denial of service attacks after calling out spammers and other companies for poor behavior. The bigger shock wouldn't be getting this sort of attention, because most people double down on their dickery when you call them on it.
About the only reason I host my blog on Google's Blogger is that they can handle any amount of traffic. The day one of my posts goes viral, I'll get the advertising from the billion page views. Also, the day my blog gets attacked for making someone angry on the Internet, they'll really be attacking Google.
Good luck with that. Also, Google shows the attacks as page views, and they are attacking more than one, so thanks for making my blogs more popular!
