Back in the internet dark ages, it was fashionable for some hobbyists, having added an ancestor named Drogo to their personal family tree, to also add Mrs. Drogo. When GEDCOMs were discovered, Mrs. Drogo and her many, many sisters migrated to WikiTree. We don't know her given name, nor her last name at birth, so she became one of many people named Unknown Unknown -- about whom nothing was known but the name of the person she (may have) married, and likely nothing will ever be known.
I understand current WikiTree policy is that we don't take Mrs. Drogo's LNAB and recycle it for someone completely unrelated. The explanations on this page make sense.
But there is a whole series of G2G conversations, dated seveeral years before the current policy, on "Recycling Unknowns" -- when to do it, how to do it, etc -- most all of which would appear to violate the current policy.
It would be most helpful if these discussions could be retired, or if that is not advisable, at least have a note appended that the discussions are out of date, with a reference link to the current policy..
NB: I see that G2G has helpfully illustrated this issue by pulling up, under "Related Questions" below, many of the discussions whose assumptions about recycling are not consistent with current policy.
