Bluecat posted screenshots of his work on his game as I recall and even when they were posted to the forums the mods didn't care.
The only way to get *around* this rule, (and keep in mind you said anything) would be release a small update. It doesn't have to be too much content. Maybe an event or two. Call it a pre-update update maybe? Well, I'm just throwing out the only option I think will work for you.
If I do that I will have a horde of people at the front of my door ready to kill me xD
Not only that, but a lot of people will think this 2 mini-events update is the BIG UPDATE everyone is waiting and to be honest, 90% of the people will hate it.
I'm not talking about posting screenshots, I'm talking about a private chat or something where I show everything on a Livestream or something like that. One of the reasons I'm not showing THAT MUCH stuff is that I want to surprise people, so It won't be public.
But again, if this gets the abandoned tag I can't do more than that, I will keep answering questions here and showing stuff.
I won't deny that it would be horrible to receive the tag because there will be a horde of people coming and basically saying that they knew that it was abandoned, people really believing that it is abandoned and etc. And I deny to deal with those xD
