Are my comments gone in a better place?

Hi, not sure if it's the right place where to ask but... if I look at my user profile states 464 comments, however only 2 are displayed in the history? I'm the only one with such issue? My profile is: Now, I'm not saying that I'm the most awesome commenter ever, but you know, I'd like to follow the discussions I was in in the comments... Can I get anyone from the support team look at it?
