I'd challenge it but admin don't have the decency to contact you and instead hide behind an anonymous notification.
Woah - settle down. I asked one of the moderators to remove the images after which I said I would send you a private note to explain why they were removed. I have now done that - apologies it wasn't done earlier, but I was getting my kids ready for school.
You are welcome to discuss any problems you have with moderation - but in a thread is not the correct place to do that - please contact me directly.
Apologies folks. The pictures of the plans were deleted because sharing them allegedly breached copyright. Which is absolute nonsense considering they're already shared in the public domain. Were shared without being altered and clearly included the marks of their owners and were shared for information purposes only with no commercial benefit.
Yeah, that's not how copyright works. Just because something is "already on the internet" does NOT make it "public domain". You did not specify or credit the author or the source of the content, nor have you identified who are the actual copyright holders.
In my experience, architectural drawings often have multiple copyright holders (the client, the drafter, and perhaps even the the 3rd party hosting the images).
If you look carefully at the images - there is actually a copyright statement included on them. Unfortunately it is too small to read - but I think you'll find some very important information on there relevant to this matter.
