Thanks for your response.
If it's only based on the activity "on the block" it's great. I would love to have a tool to see the engagement score (as it seems similar to @abh12345 engagement league formula) of anyone I want to check.

The only problem I see is that if the tool is used by a lot of people to upvote or follow (and as a consequence being on the Leaderboard of that list has a certain return value), some will find a way to make it to the top by reverse engineering the formula and abusing it, but that's the price of glory.

Looking forward to be able to check the score of anyone with a Steemit account, I won't be able to help point out discrepancies in the formula before having access to that.
