Uh I tried OP's method and deleted every picture. Still shadow banned. Hopefullly a two week break will fix it.
Did you try and do a fresh upload and test with only 1 working tag.. e. g #chair or some bullshit? Because if you use tags and say 1 of 15 tags is banned then your post won't show. Also some very popular tags are banned.. i think even one like #love or something... test on a single normal tag to judge.
