No.
These were within the last month.
There was interaction with my comments.
I know I'm banned from a couple -it doesn't let me post on them. And I unsubbed from them. And I browse by Home/my subscriptions.
Is it possible that an instance could simply remove an entire subject or posts and not have it logged?
I know I posted comments.
I know they were replied to.
I remember the quotes I used by the person who I was commenting about.
Poof. Vanished.
I guess I average about 10 comments a day.
A month missing in my comment history is....strange.
And I'm certain those weren't the only communities I commented in.
I also regularly comment in Linux and android and privacy.
