If shorena removes their rating, I am 100% sure that lauda will be at 0 then.

No, if I remove my rating Lauda will be at whatever score they had been before my rating. Well plus the additional "points" due to the rating by Vod.
There might be reasons. For example if a long standing, highly trusted account gets hacked, it's useful to get the warning (orange color) after a single feedback, as that can be quickly left.
Interesting point.
I gave Lauda new positive trust and the ? ? ? went away.
If what you posted was the reason behind the ? ? ?, Theymos may want to tweak the algorithm.
Counter-Ratings like yours (even though you didnt word it as such) are part of how the system works. If someone thinks my rating was given unjustified they can leave an additional rating to reflect this.
