I never played EVE Online, but a friend of mine told me a fascinating story. When players exploited a "loophole" in the rules, the game didn't change the rules. They introduced new tools.
Mining is an inherently risky operation, because mining ships are poorly armored, and generally defenseless. One risk is that someone can destroy your ship, and steal your hard worked for cargo. However, attacking someone in a civilized system would brand the attacker as a pirate, and NPC police would instantly warp in to execute justice. Even if they were able to escape, it would be difficult to return.
The pirates got clever, though. What if we were to load up a ship with explosive material, fly next to a mining ship, and detonate? The mining vessel would still be destroyed, but since it's an "accident", it won't summon the police. A partner in crime can scoop up the debris, and we can share the profits.
Now, EVE admins could have simply said, this is cheating, and you can report players who do this to our administration. But EVE has a famously hands-off approach to their game, to the extent that when a clan decided to declare war on a high traffic area, the administrators thanked them for the heads up, and promised to allocate additional server resources to handle the load.
Instead, EVE created a new class of ship that would prevent warping within a certain range of your vessel. This would create a buffer zone between you and hostile pirates, giving you equal footing.
I may have some of the details wrong, but hopefully you can see the point I'm illustrating. One strategy is to say, "Trying to circumvent the rules of the platform will result in a ban." However, this requires a moderation team. Furthermore, such decisions are subjective, and even the moderators can be gamed.
And finally, the spammers have an asymmetric advantage that Facebook will simply never be able to beat. Posting something is easy. Identifying things to take down is hard, and requires ten moderators to every one spammer.
Facebook should take a lesson from EVE Online. Instead of setting up censorship rules they can neither enforce or maintain, they should invest their energy into introducing game mechanics that accomplish the goal for them.
So in effect, yes -- I definitely agree!
