right, but the problem is tied to the platform where it limits bandwidth usage on the steem blockchain based on how much SP you have, so that new accounts can't come in spamming and crash everyone out of using steemit. It's also a way to ensure sybil/ddos attacks are pretty much useless here, but the side effect is that sometimes normal people run into the limitations, so these tips are given to help minnows avoid that.

Just to reiterate: you could have a 1tb/sec connection with unlimited data and still run into this problem after using a few mb of bandwidth on the blockchain, so you either need more SP or an understanding of how it works in order to avoid the problem, at least until it gets changed some more, which is another story.
