The truth? I followed a bunch of drunk Dutch guys through a hiking path in the woods after going through the tunnel to the other side.
It was a hike to get to and there was a service road next to it.
On the topic of legality, I can't tell you if it was for public or not.
Halfway through the Kemmel straight under the TV screen there's an area, usually quite crowded, which is definitely public since it has garbage bags, toilets and security people. Said security people seemed to have no problem with spectators standing outside this area along the straight. This is from FP3:
On the same side there's also an interesting spot right at the braking point before Les Combes, you get a very good view and you're really close to the cars. Ignore the awful quality of this picture, this is just to get an idea of the spot:
Speaking about legality, it's quite surprising that they still allow people to sit and stand on top of that hill alongside Blanchimont and Bus stop, it's very steep with crumbly dirt and big rocks here and there. One foot wrong and you're having a really bad time, taking other people with you on your way downhill. Or you send one of those rocks flying over spectators' heads.
I was annoyed with some people partying in the Green Camping area Saturday after the accident but at the same time it was shortly after and many people probably didn't even know about it. People also react and handle traumatic things differently. The vast majority of people I saw were very somber and quiet. There was a lot of stunned people walking around.
I agree. I was standing in the middle of the Kemmel straight on Sunday and it was quite touching to witness the silent applause to the ambulances, fire department and medical staff doing the parade lap and the minute of silence. Standing in the middle of usually loud dozens of thousands of people and only hear the wind through the trees was really striking.
A few people took the Johnnie Walker plastic signs on the tire walls after the race and used them as a sort of surfboard going downhill from Raidillon to Eau Rouge, covering several meters (it's that steep). Not really classy after what happened, but I guess they were just too excited about being on top of one of the most famous corners in the world.
Overall, I felt like people have been very respectful, also considering the amount of beer per capita in there.
