Are you referring to the posters' profiles? If so, you click the poster's name at the top of the comment and up comes the profile with the list of all stories by that author.

If you click in the search bar at the top of the profile and press your space bar, you get a list of some of their recent comments (if any). You can press any key and the list will contain comments with that letter in the title. I use the space bar because every title has at least one space.

Provocation is indeed a common tactic. Too many people fall for it.

I know a way to read posts from those who have blocked you.
