I agree with nexuscain spamming a blog and spamming someone to vote is the exact same thing. People always have the choice of whether they vote for you or not just the same as people always have the choice to plus your blog or not. Or to read your blog. Etc
There's a stigma against one, while there isn't for the other.
And either way, the rule has thus far been irrelevant, as not a single person in the cast has even made a nomination blog yet, nor have they spammed anything.
Lastly, these rules were set since the before the beginning of the game under these parameters.
At the same time its his game as long as the rules were expressly laid out before hand what is and isn't allowed then there really is no argument...Hopefully moving forward with future games though he corrects it because the only way to make it truly fair would be an all or nothing approach since as we have said there is no actual difference...
