What's with all the sub comments?

Anyway, after some thinking it's probably just an address collision due to my own stupidity.
People don't know they can click "Notify" at the bottom right to subscribe to the thread.
Ugh not this again. Here, have a link for your viewing pleasure:
https://bitcointalk.org/index.php?action=unreadreplies <-- that's why people "sub". They don't want an email from the Notify link.
Just to make this clear, this is commitcoin protocol vulnerability, not bitcoin one.
Still interesting nonetheless.
