Was comparing some hotlaps on lfsworld, and came across this one.
On SO2/XRG it says: "hugoluis's hotlap was not valid and will soon be removed." The replay was uploaded 16-06-2009. I checked the replay, but can't see anything wrong in it.

Only thing I could see was the small contact with a wall before the timed lap. Such a hit should invalidate the next lap. I guess the in-game HLVC check didn't catch it, but a server-side check did

redid the validation check and it's ok now

Actually there are more like that. E.g. SO classic rev / XRT by [d9]. The date is 15-06-2009, only 1 day diff compared to hugoluis. I'm guessing there were problems around those dates and there are probably more of them...

I've had a look and found 25 other hotlaps in the same 'check state'. I've reprocessed them now and they appear fine.
