Steemit Condenser - Grey out vote buttons after seven days

Repository

https://github.com/steemit/condenser

Components

This suggestion is about the voting of posts/comments on Steemit, so for every Upvote- and Downvote-Button.

Proposal

An upvote is only worth something if it takes place in the first 6.5 days. With a downvote, you have seven days to make it work.
After seven days you can still vote on a post, but without effect. That's why I suggest graying out the Upvote and Downvote buttons after seven days on steemit.com.

Mockups / Examples

My suggestion would be to colour the buttons grey. Here is the example of the Upvote button. I took the mail preview of this Post from @rivalzzz and incorporated the corresponding change.
The first picture shows the current situation. If you scroll to the right, a new image appears, where this button is grayed out.

^{scroll to the right on the picture to see a possible version after implementation}

Benefits

Especially newcomers are confused by the still existing possibility to vote, because after a short research on the result come that this would bring nothing more.
Without offering an advantage, the vote buttons lead to confusion among users. Just as with the Resteem button, which also disappears after seven days, it would be advantageous if the Vote buttons are greyed out, or if you go on it would also disappear.
