That raised my eyebrow also.

In the past I've heard similar statements and had people point at 'cooked' raw data as evidence of editing.

'Cooked" generally means raw data with warts removed, the raw data is still available, the cooked data is what's on offer as the primary data of record - typically it may have had sensor errors and saturated bursts removed, undergone light smoothing filtering, and perhaps been geolocated to earth coords rather than retaining raw instrument attitudes, etc.

'Censoring' can mean 'no longer linked on public webpages for easy downloading' - generally the raw and cooked data is still on servers and accessable by direct FTP.

I'd be interested to know what specifically the GP actually meant by that throwaway assertion.
