The report basically is "who am I the parent author to the most". The idea is to find people summoning bots.

I don't maintain a list of them (although I thought about it in future updates), but I have used this a lot on my own to find people spamming things like !lol and so on. It is just something I use to find patterns.

The Anti-Abuse category is just a sample, there are a ton of tools I don't make publicly available and Anti-Abuse will be locked down to a very small group of people if this goes further.

Should the threshold be lowered here to say 5 times a day?

This will going to be configurable, but this is the default I use in my backend system so I just copied it here for now. Again, these Anti-Abuse tools won't be general use and are just an example.
