I think I was clear enough presenting the options I knew to help this guy.
No replies.
Now that I have prepared the quickest option 1, I receive all sorts of 
contradicting replies.
Why not before I did the job?
So, my conclusion is to suggest you to do it exactly as you want.
You know where the data is.
I will certainly not manually enter 1000 entries in OpenStreetBugs just 
in hope.
But someone may know how to use OSB API. Or that they have none.
And in that case, send OSB the file zone30_BE.asc. Or split and share 
the job...

Is the error having no speed limit or having a dummy node showing there 
should be a limit?
I had found that way to automatically signal the error to OSMI and to 
OSMOSE and to ...?
But you don't want that.

I was doing all that because I once picked up a dead 10 yo that s.o. 
knocked down, no speed limit.

Goodbye,

André.
