Just quick note, I have purged a number of crufty downloads that were marked for deletion. These were already "unlinked" and therefore not directly accessible, but were littering up Google results. The only direct effect anyone should notice is ~300 reduction in the download count.
Most of those were old corrupt files or files that have been replaced with better dumps. The total space saved should be around 34GB.
So.. back to adding more files! 8)
