I don't fully agree with that. There's plenty of reasons for having more than one account. As an example: I own (openly) @AdventureReady & @BeachReady. Both are sister companies but I want to brand them in different congruent ways here on the Hive Blockchain. This is only one practical example, @dickturpin and @mrtats, for having a multiple account approach to the Hive Blockchain.
If it's fraudulent reasons though... I get it and agree. Having more than one account for the purposes of less than honest acts is an absolute determent.
Of course, having different accounts for different projects is one of the legitimate reasons for having multiple accounts. I just wanted to give a personal example by mentioning curation in different communities.
We have to acknowledge that some people might use multiple accounts to hide their self-voting tendencies and other fraudulent things.
Sure. These are things to consider... But on the whole I don't think that would be a reasonable reason NOT to have the ability to have another account. It's all about intent as you know. These are tricky things and the balance is an ever changing pendulum of need and want.
I gave you a follow as I appreciate your sharp intellect and the obvious care you have for the Hive Blockchain.
