If I post a the tip portion of a kydex sheath I've made and title the post "Test" and say "I'm testing a new website file hosting service" - it's possible someone might recognize what the tip of the knife looks like, but it's unlikely. I knew only that the that scabbard had two straps for shoulder carry, nothing more. I would have had to guess that it was busse related.
Because your post is titled test and is by nature testing whether or not the software, code, or forum works properly, and had no noticeable reference to anything busse related, I'd expect a moderator to question if this was literally just testing software. The moderators shift posts around that have to do with specific forums because without that, several of these forums would become Technical, political, tactical, or community very quickly, and those seeking the forums topics would have to sift through a stack of unrelated posts to get to what the forum is about. It's just the nature of organizing a forum.
Jaxx's request was fair being that he's a moderator, and being that the post did look like just a forum code test, with no direct relation to the busse forum stated or mentioned. It didn't even have to have the gladius in it, or even a gladius - if you had said "this is a new gladius sheath I finished" or put a skeleton key handle sticking out I'm sure it would be fine. Even a 'guess what busse this goes to' probably would have sufficed.
Testing code or picture hosting services with unrelated pictures here is discouraged, just because it would clutter the forum with stuff not related to busse. Which wasn't what you were doing, but there wasn't anything that clarified otherwise.
