Aliasing room → invalid_tag
Link to alias

Reason:

Room is a very vague term and seems to be tagged all over the place, if the picture is in a bedroom you can just tag bedroom, etc.

I'm almost tempted to say just alias it to inside.

Yep, aliasing it to inside might work.

Yeah inside works, I didn't see that tag.

Switched it to be aliasing room to --> inside instead and then approved.

Also, I was so glad to see this one. It's been in my notes to suggest for ages and now I don't have to worry about it. Awesome. =)
