The 24 hour window I feel levels the playing field and is for sure a step in the right direction when it was made. However maybe some other adjustments might need to be made since it seems like a few are starting to find ways to "game" the system again. It's always hard to tell.
Also another important factor is how downvotes simply remove a high reward from someone and distribute it to everyone else. Always good to bring up these refreshers and reminders as Hive continues to grow.
Also interesting little case to see between Splinterlands and BDVoter and not something I would have even though was possible.
It's a bit lame imo, I tried to not be opinionated about that in the post but it especially sucks seeing splinterlands miss out on a lot of rewards considering what they've done for the chain and the amount of stake they've bought up just so others can maximize their returns. Hopefully they'd consider changing how they go about voting the posts they curate.
The introduction of the linear reward curve was a big improvement and step into the right direction.
However, I see no reason at all to treat late votes (within the seven day reward window) differently than early votes. Treating them just equal would easily avoid cases like that of Splinterlands.
I place my 100% manual upvotes normally twice or thrice per week and thus see many posts of authors in my feed rather late.
