I agree it can be a bit creepy to see someones name on the visitors list if you have blocked them, its happened to me too..that said the visitors list has an arrow on it. where you can click on the arrow and it closes the recent visitors list. that way you dont have to see who is visiting your page and who isnt. I use it myself when I am having the kind of day where seeing blocked names are visiting my profile page. you find the arrow by looking to the right of the words....recent visitor.

the spot where visitors leave messages also has a feature where you must ok messages before they show up on your visitors page...you click on the words quick links in the blue bar at the top of the page (any page not just your profile its the blue tool bar) a menu will show up, click on user control panel...that will open your page where you can set all your settings.. in the list on the left click on ...edit options.... then scroll down until you see the words ...visitor messaging in there you can control who can leave a visitor message on your visitor page.

as for harassing posts you can report the post to a moderator by going to the right of that post that is offending to you and click on report icon. then write in the space provided why you feel the post is offending, harassing you and ask a moderator to help you. the moderators will look at the post and decide if this person is harassing you and if so they will delete the offending post.

also thought I would say that sometimes what we think is someone out to get us or harass us turns out to be just part of our mental disorders.. thats why when I report a post I feel may be harassing someone or other harm to a member I place in the report whether I would like the moderators opinion on that post. if at all possible the moderators answer me back to let me know whether the post was the way I read it to be or whether I misread it, or read too much into it.. the moderators can be a great help in these kinds of issues.
