That could be- I haven't read the books since the last one came out. This is what I'm seeing on the HPWiki:
Having embraced the Dark Arts he encountered in his travels, the former Tom Riddle, now known exclusively as Lord Voldemort, raised an enormous army comprised of followers he recruited both at school and afterwards,
That suggests to me that the early Death Eaters grew up with him as Tom Riddle, and it was just a name change. If the "Voldemort = Riddle" thing is poorly known, it's probably because no one has reason to know that his name was Riddle (like, for example, most people have heard of Stalin but haven't heard of Dzhugashvili).
The next discussion thread is here.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 84. The previous thread has passed 500 comments. Comment in the 14th thread until you read chapter 84.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
