To those of us who have been around a while, we're pretty familiar with what's allowed and what isn't, why you shouldn't release captive fish, etc. I think maybe we have a hard time looking at things from the perspective of someone just getting started who hasn't heard any of this before. Probably most of us caught and temporarily kept snakes, turtles, toads, tadpoles, etc. as kids/teenagers without any consideration whatsoever of whether that's legal. It's reasonable to expect anglers to be familiar with fish and game laws, but I think many people collecting their first few small fish for an aquarium don't even realize that they're technically "fishing" and that those laws apply.
The point is that we definitely want people who just started keeping native fish and are excited about it to stick around long enough to learn how to do so responsibly. When someone first posts about a fish that they really shouldn't be keeping, I think it'd be a good idea to say some encouraging things ("yeah, that is a really neat fish") along with a fairly gentle nudge to check state laws. If folks are familiar with that state's laws, it would also be nice to suggest alternative fish that can be collected, or vendors where fish can legally be purchased. We also shouldn't necessarily expect someone to completely "get it" the first time it's said -- might take a few repetitions before it really sinks in.
