I’m new to steem, but could developers fix this by changing SP a bit?

( others have mentioned preventing up voting of your own post.)

What if we limit how much of your SP can be used on a tiered basis.

Meaning, 10000accounts with 1 SP would be potentially more valuable than 1 account with 10000 SP.

For example:
The SP of amounts 1-1000SP, 100% can be used for voting.

1001-2000= The first 1000SP is still 100%, but the next portion can only be used at most 90%.

The next 2,001-4000 can be used at 75%
The next 4K-8k= 55%
The next 8k-16k = 30%
The next 16k+ = 15%

Or some other scale like this.
