I don't know that the live events people (there's only about two people afaik) have the time to go through the IGS and look for things speculatively. Perhaps a mail to a relevant event actor, to notify them that there's something, would be useful.
iirc, Falcon said the event actors get maybe 100 evemails each day? so just dealing with those is probably enough time spent that browsing forums without looking at something highlighted, isn't really an option.
Incentives for people to get involved ?
Umm, for Goonswarm, I was under the impression that historically, the following were incentives for Goonswarm:
1. Because they can.
2. Because it's there.
3. Because it's funny.
I'm not sure about incentives. Of course, for live events, there is the possibility of news articles, and influencing details of the storyline, but Goonswarm gets in the news as it is.
Incentives of stuff is in itself problematic, in that it takes away from player involvement. E.g. 100 titans spawned by GM intervention, means 100 titans not built by players, not defended during construction, and so on.
It is unlikely that it would ever be agreed to destroy Sansha's Nation and stop the incursions, as that would mean to end a thing that was the subject of an entire expansion. It is unlikely for the same reasons, that FW will ever reach a resolution.
Unique items as rewards are unlikely, because of how that will be seen by some elements, the whole "devgoons favouring goons" thing.
And for NPCs to defend the space for the duration, is also a very large intervention in the sandbox. It again takes away player involvement.
So, things are unlikely to happen.
but to get a "We have ~other plans~ for Nation" response, I'd recommend contacting the CONCORD actor with a mail, highlighting the topic.
