Hello.
We do check all reports and post all comments manually although we use a certain format for different types of abuses.
Automation is very costly.
We ran cheetah for a while during Steemcleners years. It was detecting copypasta and plagiarism automatically. It was a very expensive service to run.
Is it more expensive than you(HW)?
If I remember right it was something between 800 and 1200usd per month, but that was a long time ago, I could be misremembering.
