So, you read something you like, and you want to vote for it. But it only took you anywhere between a second, for a short post, to 29 minutes (for example) to read something and decide. Now you have to wait anywhere between 1 to 30 minutes to maximize your curation reward potential. And of course, think about other people voting before the 30 minute mark.
Who wants to wait even 1 minute from the time they decide to vote, to the time they cast it? It just doesn't make sense.
It wasnt for the cool down there would be 1000 bots voting in the first 5 seconds. The cool give us humans a chance the read and the post.
And you have to leave the post open in a tab or whatever, remember to come back to to later? Crazy talk. All because of bots? Let the bots ruin everything?
So, instead, there will be 1000 bots voting sometime between 15 minutes to 0 minutes after a post, over time, as bots compete for what little they can get. The solution doesn't fix the problem. It just makes the experience worse for humans.
Either that or no rewards left for people. This way you have a chance. But bots are not as good as you. You will always have an edge for picking good content.
How do you draw the conclusion that putting constraints on the time when a vote is cast does anything to help solve that problem? It doesn't. The bots just wait until whatever amount of time elapses before voting. There will still be the same number of bots voting, no matter what you do, as it costs little to run them. What a delay does is actually give the program time to analyze the posts before casting a vote. It actually helps the bots win because sophisticated logic to become the best bot will involve analyzing patterns and content. Humans excel at pattern recognition and it may take a human seconds to recognize "good" content vs. a bot. Thus a human should be able to make that decision promptly.
Time constraints just makes it a little bit more likely, and I mean only slightly more likely, that you'll decide to vote before a bot, because as a human, you are impatient. And when you vote, you'll have to vote before the bots to earn anything at all, minimizing your curation reward. But if you have only a little steem power, it is irrelevant. The first bot with a lot of steem power will earn the most.
For more and more reasons, there is no benefit to the "cooldown" at all.
Not sure if you know that also the earlier you vote, the ore of your reward goes to the author. If you vote in the say the first minute %100% of your reward goes to the author. At a 15 mins you split the reward 50/50 with the author. After 30 mins you receive the full reward. So and the bot maker have to determine how much of your reward you are willing to sacrifice for being first to vote.
