Thank you for removing your vote! It's necessary to remove the vote because of how the proposal system works, each governance vote you cast divides the value of your support. Supporting multiple proposals diminishes the impact of each vote (example: If you vote for 2 proposals, each requester receives 50%, if 3 then 33.33%, etc...).
As explained in a previous post, due to a bug not fixed yet, if the proposal is deleted, the Blurt Power support value from your vote is not automatically released. By removing your vote before the proposal is deleted, you ensure that your Blurt Power support value is not lost. Your support is greatly appreciated, and I'm glad you're enjoying the platform's development!
Thanks for the explanation! :)
