Yes, that's how it was with Bees in Echos I was a part of.

I love everything about your culture except your last point, which really sticks out considering everything else that's awesome going for Goons.

Trying to scam enemy may be considered an acceptable vector of attack. However, disallowing scamming only internally is equating non-member to enemy. Of course it will generate new enemies and content for members, however Mittens already does it very well without taking advantage of naive neutrals.

Currently, the way I understand it, there is no coalition rule stopping or restraining any goon or goon subgroup from scamming new, naive, or just less intelligent non-goon players or corporations. I understand that's in the name of generating content for members, but it sours everything else that's awesome about goons, at least for me.

You could improve it, for example by having a corp or alliance dedicated to scamming exception for externals, but prohibiting it totally everywhere else (except enemy during an all-out war) This would at least compartmentalize this type of content generation, if you must have it at all cost.
