1) You're wrong. Pictures are evidence. The FAQ claiming that pictures are not proof does not stand and is different.
I may or may not agree with you. However, if I didn't put that in my post, someone would jump me with "OH MY GOD PICTURES ARE NOT EVIDENCE". The way I did it was simply... simpler. Then again, I didn't expect you to attack me for that. You're one of the few RE'ers who usually respond to the point instead of nitpicking on words.
2) Yes, some dishes are not functional.
Some of them, quite possibly. However, as presented by the picture, which (as we have just established) constitutes evidence for you, there exist blocks of flats in which most flats have their antennae situated like that. Why do they keep clearly useless satellite dishes?
No, your inference about the intelligence of those in such houses is unfounded.
And again, nitpicking. My "inference about the intelligence of those in such houses" is also irrelevant to the point. Feel free to cease your attempts to derail this thread.
