People should have the common sense to spot scams cause you cannot push everything for it.
I'm not just talking about scams... i'm talking about things like delete bad product reviews and such on...
I think you would be surprised how much trolling happens. I'm not sure who I made mad but someone the last week has trolled me a little. I kinda get the last laugh with self-moderated as I can delete troll in less time then it takes them to make a post.
But for example I had a hardware wallet review... someone with 1 activity posted a paragraph with links pointed to weight loss sites (guessing from the typing did not open them). I'm guessing it's same just different name who has done it 3-5 times during past week. So not a ton but if I did not have self moderation on I would have some horribly off topic and trolling remark until staff can get to it.
There is very valid uses for it. Just be careful if it's buying something. But in all honesty you should always be careful when buying something.
