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.
