Per DXCC rules:

5. Deletion Criteria

a) An Entity may be deleted from the List if it no longer satisfies the criteria under which it was added.

+ Were these criteria in place when BS7 was added to the DXCC entities list?

"For the purposes of this award, it must consist of connected land, of which at least two surface points must be separated from each other by not less than 100 meters measured in a straight line from point to point. All of the connected land must be above the high tide mark, as demonstrated on a chart of sufficient scale."

+ or were these criteria established after BS7 was added to the DXCC entities list?
