Wow, ROI limit is a fantastic addition! I fully agree with you that -10% is an optimal number to balance between safety and abuse.
I also have one idea for the Front Run the Bots feature - maybe add a column that indicates to which bot the user has paid the vote. This could be useful because there are individuals that flag posts supported by certain bots.
Thank you for your hard work!
P.S. I've just noticed that the Max Post Age column is no longer visible, I'm not sure if it is a bug or an intentional change.
Good idea about adding the column to indicate which bots were used to the front run feature! I will definitely add that to my development list.
Also thank you for pointing out that the max age column is missing (as have other commenters) - that was a mistake and I will get that added back in asap!
