Hi @neavvy I feel that GTLR though it may be limited is only a use case a demo of the possibilities.
I would go through the github link and maybe we can tweak it to track spam and abusers on platform like steemit.
Another application could be to identify fake review writers on other platforms.
I know I am digressing from the topic a but but I find the uses and possibilities immense by tweaking the code as it is open sources and has listed on Github

Nice post buddy and good luck to you dear @neavvy
