The activity widget will only show journals, questions, photos and thought bubble type stuff. It won't list your group posts but it will say what groups you have joined if you have them set to public settings.
The search function will bring up the same kinds of posts. It isn't designed to pull up all posts by a certain poster and it may or may not bring up group posts from that person. However if your screen name shows up in a group description or is written into a reply or comment (not a quote) then those posts will come up for sure. Deleted posts are gone to everyone except CM. They can still pull up most deleted content with the right information to find it. They would need a reason to do so
To see what shows up for you, you can enter you screen name in the search field at the top right of any cm page. Also sign out of cafemom and then doing a google search for your screen name. You will see what is showing for you.
