Joining the spectators was introduced by "OvalJunkies" IIRC as a rule on just their server, but I think since then its become more common overall, lets face it, its not realistic and race drivers really need to learn what yellow flag means.
For me when I see a yellow I don't always lift, but I will check the minimap for stationary cars ahead and be ready and expect to slow/break for stopped or turned around cars.
However to me the more important rule is "no overtaking under yellow flag" it seems whenever I go online (not that often lately I know) people can't wait to overtake yellow flag or not, it seems a pile up is just a good excuse to gain a few extra places regardless of flags, shocking!
TVE the 2 points you made in the 1st post, I would have done exactly the same.
