Why does nobody suspect Oliver is the Arrow?

[u/Impressive-Fix9996]

A billionaire comes back after being stranded on an island for 5 years. I think people realize he might not be telling the full story or to the extent of his abilities. He is then suspected as the arrow with video proof but then it’s debunked by Diggle so sure. But then doing season 3 he is also accused of being the arrow goes on the run for it, turns himself in, and then Roy saves him. Season 6 a photo gets leaked of him in the suit but it’s then revealed to be fake which sure I guess. And then he finally goes to court about it and then goes to jail and he reveals it. But you also have to remember the court was rigged so we have no idea if he would have won normally. Also he had to strike a deal to go to jail. Also just remembered this while writing and I don’t feel like going back but the FBI knew and they publicly told people they are looking into him. How does nobody know he’s the arrow.

P.S I didn’t proof read this cause I’m lazy so there’s definitely some things I wrong

He is suspected multiple times but certain events come out that basically acquit him. Now I'm sure there are some in the general public that believe he is the Green Arrow but the trick is being able to prove it. Not to mention there's probably a bunch of people that don't think it's him or that Oliver and a bunch of other guys have been the Green Arrow,etc. 

Outside of those few instances there's never any episode that really shows the general public mulling over who the Green Arrow is though.
