Most of my posts have disappeared

Sunday, Oct. 30

Hello.

Just wondering why most of my posts have disappeared.

I joined recently and in a couple days got an automated message than I had posted more than 10 times. My total posts were about 15 or so.

But when I logged in today, I see that most of my posts have completely disappeared. No trace of them left at all.

FYI: I self-deleted the couple of my posts that remained.
