I m not sure, you will even read this or not, but still wanted to tell : You are working against spammers, which is fine, but would it not be nice to also reward people who deserve it, by using certain percentage of your vote ? Say you use 60 percent in flagging and 40 percent to encourage ?
I run a charity bot named @thehumanbot with this initiative, encourage people to write original, if you want to join the hands.
I have read about @thehumanbot and I must say that platform is great sir. :)
