If I recall correctly, there is a dedicated CG thread for digital artworks of varying quality so that the more professional flagship threads don’t risk becoming something less than professional for military matters, such as Reddit or DevianArt.
Yes, but if someone is asking whether something is a CGI because they're not sure, then that makes it slightly different.
That said, once something is confirmed to be CGI people should refrain from commenting on it in a flagship thread.
These interactions should ideally go:
Person 1: "I saw this picture, is it CGI"
Person 2: "Yes it is CGI"
NO FURTHER DISCUSSION AFTER IN THE THREAD ON THE CGI.
Things do get a bit more dicey if they are speculative CGIs of an "in emergence" project or a project that we do not yet have good pictures of, which in theory J-36 is, as one could make an argument that they are part of the constructive discussion around the details of a project.
IMO so long as discussions do not become too tedious and derail a flagship thread too much then it is tolerable, and it means people who want to enter a conversation should really exercise restraint and have a damn good reason for trying to talk about it.
