Did the GDB wiki user list get pruned?

Did someone cleanup wiki users?  I used to have a login (unless I am
going senile!) and have edited the wiki (especially over in the old
Archer section bits) quite a lot.  But now my edits are like:


host86-146-234-176    Add archer-pmuldoon-python-value-infcall branch and description.

(from the "Info" link on a wiki page).

Where the username (in this case, my old one) has been replaced with
the originating host.  It's no big deal - it was trivial to create a
new one and get editing privileges setup.  But I am curious about
what happened there.  Apologies if this has been answered.  I did a
rudimentary search of the mailing list and nothing came back that
looked promising as an answer.

Cheers
