Thanks, Hersfold.

Delete redirect pages from my old user subpages  and  and the user talk subpages  and .
Delete my user talk archive subpages and all other user talk subpages .  Note that my talk page is structured so that archives are copy/paste.  Therefore if you left me a comment last year you will still have it in your contribution log (something which I think is generally important to maintain as long as the user who left the comment is active, barring truly exceptional reasons to delete user talk history).  
Delete my user subpages, listed here. Be careful that if the subpage is a redirect to a different namespace page, such as a Signpost article, you delete the redirect but keep the actual page it points to.
Blank my userpage and delete the page history, which is several hundred revisions. I'm not sure how you want to do this, but when you're done there should be a single revision with an edit summary of "blanked the page" or similar, and nothing from beforehand.  Leave the full protection in place.
Blank this talk page.  Leave the revision history alone because, as above, I believe it benefits other people for it to stay, even though it does me no good.
On a non-technical note, thank you for doing this.  It is unfortunate - and despite what others might think, not entirely my own doing though certainly that was part of it - that my extensive contributions to the encyclopedia have been overshadowed by other issues which should have been forgotten long ago.  I hope that as a result of my action, those issues actually will be forgotten.
Unblock User:Arthana. I'm trolling now, but seriously, he is innocent, and I like to point it out whenever I can get people's attention.  He is not the only innocent user who has been blocked, but to my knowledge he is one of the few who didn't manage to get unblocked.  If my attempt to become an administrator had succeeded, I would have unblocked him.
In the interest of disclosure, I will also ask for deletions of userpages belonging to other accounts I've operated.  I will do this confidentailly through the proper channels, but I note here that it is being done.
Goodbye, and I hope the work I did here will benefit people in the world out there.  (Shalom)
