If the person posts a visible comment you can't press on it and check their profile, because he/she obviously hid herself/himself from the search list but then the ID is somewhere in the page source. When looking at the page source, look for this string with the person’s name in it:
"comment_author">John Doe</
and the very next string in the sequence like this
rid=1234567890&cid2
has the ID in it in this case 1234567890.
Between these two strings, you will recognize the comment itself, the date and time posted etc… Since this sequence is true for all the comments on the page, make sure you’re matching the ID with the appropriate comment.
