The fact that I have a profile that I never created lets me know they are a shady and opportunistic company. I once had to host something on SlideShare for academic purposes and they used my information from that account to create one on their site.
This sure is not a bug, I am glad they got caught.
I once set up a legitimate account to view something. I got spammed so much before I shut it down that it forever tainted my perception of the operation. Even that seemed opportunistic.
