Where do you get this idea that Youtube and Daily motion do not reward based on viewings?
You contradict yourself in the second paragraph.
Oh, so, upvotes on content that is old, should be rewarded, in your opinion?
Ok, so, propose a mechanism by which this cannot be abused. Every rewards system has to have antiabuse measures. Each different mechanism requires a different measure.
I have thought not that deeply about how to reward ongoing upvotes, but, I think you also just stated that subsequent upvotes do not assign rewards, only advertising. The advertising is a mechanism of proof of service. So that comes back to what I said: that the ongoing rewards mechanism for content has to be based on proof of service, not voting. A voting mechanism for rewards has entirely different constraints, and it is not for nothing that Steem has settled on 7 days.
You will have to do a lot more creative thinking to offer a substantial potential solution, and your attitude of adversary will also have to change if you want to gain access to your ability to think creatively.
Youtube pays upon # of ads viewed for more than 15 secs, not on immediate views of the content itself.
Where is the contradiction?
So is youtube wrong when an uploader of an ATG video keeps ripping the rewards of his great work?
Limiting to 7 days and even 2 months incentives the spirit of spam that ruined Steemit and tsu.co.
There must be no time limit on rewards.
Choosing votes over the youtube criteria might still be fine, but must not be limited with time.
Youtube is a means of passive income while Steemit is a means of frequent creation of spam.
Obviously there is spam content on youtube and quality content on Steemit, but their corresponding part out of the wholes differ because of the difference in the rewarding systems.
Youtube will keep beating Steemit and everything similar to steemit or tsu because of it.
Your proposals are farther from abuse prevention than mine are, and I never claimed that my proposals are perfect against abuse, just better than Steemit and your proposals which are too similar to Steemit in most of its faults and even add a new fault or 2 and then some complication.
