Thank you for your constant vigilance on this issue, Currawong. I looked again in my Edit Subscriptions page, and this time I see that three most recent threads I replied in is set in Immediate frequency. Checked the whole list of my subs, and that seems to be the only ones that have changed by its own without my input. For what it's worth, It's this thread itself, the official anime thread and the themed monthly avatar discussion thread.
I've since set the frequency back to Site Only.
