I do that shit when I have a web interview. Put up a guitar just visible in the camera, a small bookshelf, a floor lamp, make sure my tennis bag is visible despite not playing in ages...
Whether they realize it or not, people do take this stuff in. Not sure why some algorithm based on these very same interviews wouldn't do the same.
I did the same, but they were not impressed by my Obedience extreme sex bench 5000 with restraint straps. I even told them the sturdy bench is made of durable, heavy-duty steel, capable of supporting up to 400 pounds of weight.
