"Am I allowed to ask who is doing this thankless task so I can thank them?"
That would be me. I took it upon myself to enter the full run of the Drabblecast into ISFDB, and I've kept it current ever since.
I can assure you that every item in the database is entered by hand and no bots are involved. There is one exception: I think they have a program that scours Amazon for new releases, but even then, every item must be manually approved by a human moderator before inclusion.
To be eligible for inclusion, a book/periodical/whatever must be in either physical or downloadable form (ie, Kindle, PDF, mp3); straight-up webzines are ineligible (with a couple of exceptions made for SFWA-qualifying markets like Strange Horizons or Tor.com), as websites are ephemeral and unstable. My own ISFDB entry is missing several stories because they appeared only on the web, and wouldn't be eligible for inclusion until they're anthologized or collected in ebook or physical form.
I told you all of that in order to tell you this: that Derek is indeed sometimes credited as Derek and sometimes as gunsofchekhovia, but it goes by whatever Norm says on the podcast itself; the website is irrelevant. If the Drabblecast site vanished tomorrow, all that would be left are the mp3 copies on various iPods and PCs, and so that's what we go by. If Norm calls Derek Derek, then he's Derek; if he calls him guns, then he's guns. (Sometimes, it takes some real digging to find out who some of these people are, if I even can.)
I've actually done a lot of the SF podcasts as I listen to them anyway when I'm out walking or when I'm writing. I've found it's best to listen rather than just enter the data from the sites. Early Escape Pod, for instance, often had little book reviews tucked in at the ends of the episodes that aren't mentioned on the site; their database entries (listing only the fiction) were technically incomplete until I heard them and added in the reviews.
Anyway, long story short, there are no bots involved, assuming you believe that I'm human.
