They may be more blogs speaking about it but I wasn't aware of their existence. Please, send me the links, I would be interested in reading them. π
Also, Steem limits the blog's quantity, comments and transactions you can make depending on the quantity of SP you own. The more you have the more you can "spam" but it would be like shooting a bullet in your own foot because you would damage the blockchain you have invested money in. I don't see any kind of wide spamming actor in Steemit and I believe these 2 million transactions have a meaning so far.
