Are you using the full desktop website, the mobile website, the Android Central app, or the AC Forums app?
If you're on the full desktop website, you can either click on the Participated button, or click the "Posts" listing under your avatar. I see 9 current posts for you. Did you have a lot more than that? It doesn't appear that any Mod deleted posts, because I'd be able to see that.
I'm also moving this to the Site Feedback and Help forum, which is where the site admins check for problems members may be having.
