Scams aren't moderated by staff so you should leave those alone if you become a mod but feel free to leave negative feedback on scams or potential ones.
Ya, I'm aware of forum policy on moderating scams, to be honest I don't see a lot of "scamming potential" in the politics boards so I wouldn't expect there to be much "scam tagging" in that board!
It's very easy to get dishearten when your accuracy is falling and there's no way to verify why, and especially in Politics and Society due to the sheer amount of spam. Although, 257 good reports is still a very respectable number.
This was kinda of it for me. As mentioned there is no way to know why and it is a little frustrating tbh. I didn't mind reporting in an effort to try to help clean up those boards but I certainly did not want to waste anyone's time. Based on not wanting to waste anyone's time and the fact that the merit system dropped I decided to reduce my reporting and just wait and see how things go.
As I enjoy a good political debate a dedicated mod to the politics board seems like a really good idea and whomever it ends up being you will probably see a bunch of reports from me.
