Any content that isn’t worth discussing is probably not worth rewarding.

I respectfully disagree on this. How do you envision a discussion on articles that merely describe procedures in a how-to fashion?

To minimize abuse and/or delegation to bots, only accounts with simple posting authorities consisting of a single key can qualify for activity rewards. If you attempt to use advanced multi-sig configuration on your posting authority then you will not quality for activity rewards.

You won't achieve what you want with this setup but merely kill businesses such as Streemian.com that NEEDS this feature for onboarding people that are using RSS-capable blogs. If this change goes through I can stop working on Streemian.com right away because I can't make any money out of the people I bring into Steem. This is really bad!

Let me quickly describe to you how the profit model of streemian.com works:

1. Onboard new users
2. Create an account for them (that they control)
3. Have 'streemian' as posting authority
4. Crosspost content from original sources of verified users
5. Let the original users gain profits in SP and SD
6. Use the original users accounts to upvote our own content and get payed by Steem.

This means, the more people, we bring in that produce good content, the more profit they make and the more profit we can make by upvoting our content.

This however requires multisig hierarchies so that the original poster can use his account in full.

On the other side, you want to prevent bots from voting. Well, I must tell you that won't work because I can replace compromised posting accounts anytime. That means I simply share the same private key with my bot and I will still get rewarded.

Hence, this needs reconsideration!
