You can still find them through your post history I think, not sure how easy it is to locate to them now. Unless you mean they've deleted those too now. I saved mine a while ago because I didn't know what they were doing with that but yeah there were a lot of people who mostly posted in the blog section I think and they removed a huge chunk of the forum activity by doing that which wasn't a great move.
I checked your post history, but they aren’t showing for me. The poster of the blog and the mods were the only ones who could see them, and they were all in a hidden forum. I‘m not sure what happened, but I know that they wouldn’t have been deleted - they are all still on here somewhere in post form instead of as blog entries.
