Ah, thank you. So at any time someone, say a checkuser, could have asked her to provide confirmation...

Just out of curiosity, can someone explain to me the "committed
identity"
that CharlotteWebb has on her userpage? Would this be something that

be taken into consideration, or is it just to prevent account
hijacking?
See [[Commitment scheme]]. It means that at some later date, she can reveal her true identity, and in such a way that we know it's been her true identity all along, and not (say) the identity of some imposter who hijacked her account at some point.
What she's done is prepare a statement, such as
I, Cherie Wilcox, dob 1/23/45, of 123 Main St., Busytown, USA, am Wikipedia User:CharlotteWebb.Then she's taken the SHA-512 hash of that statement, resulting in the number 2bc40c120f424e1a6f5ef1f38ca718580900698db318f1ceeda555 f7613ee4251e90accbe33b741ed8984982f37a040e951e35a8573d4a68b01b63c 19ad7e548. If she ever releases the statement, any of us can verify that it has (and has always had) this hash. Until she releases it, no one can come up with any other statement which has the same hash, or predict what hers says.
Well, confirmation that her account had not been commandeered.
