This surely a great change.

It would be great if you mark the alt accounts and blacklist them. You can track the alt accounts easily as most of them have a very predictable nature. Like-

• No engagement with other users or community.
• The posts are low quality or shows no proof of brain.
• Repeating same type of posts.
• Delegated around 1000$ worth of SP for the extra 5% bonus.

You can easily filter out most of alt accounts with these behaviors. Account with less then 2500SP delegation should be screened so that they cannot drain the voting power by cheating.

Whatever, this is just a suggestion from me, which I think, should be considered. Thank you!
