NPC that helps players to not get scammed

[BoomKid8]

I've seen many instances of people on the forums asking for help because of falling for scams such as Co-op scams and trading scams. I feel like it might help to add an NPC to the hub (or add more dialogue to the Security Sloth) that simply gives advice to not fall for such scams. For example, a reminder that you can't kick Co-op members easily, or that you should take a close look at each item in the trading menu before agreeing, etc.
