The "Roguetown v. Loguetown" issue can be summarized in one word: DUH.
Hellsing's manga has the name "Alucard" written out, if literally translated, as "Arcard". Elaborating on that is "Arucard", but since we obviously know "Alucard" is an anagram of Dracula, which was mentioned in the Anime series and is clearly represented in the Castlevania series, reverting to an incorrect translation makes a studio looks stupid. It's 4Kids job as dubbers to correct the mistakes made by Toei and Oda, or at least, the unintentional mistakes (Don Creek v. Don Krieg, DoFlamingo v. de Flamingo), even if 4Kids makes its own mistakes in the translation. :/
