If you're that concerned, when you close your account, you user name is deleted and replaced with member1234 or something to that effect. It shouldn't be that big of a deal unless you weren't smart enough to use a fake name.
Oh, I see...
You can also change your user name one time if you PM Petra and clean her dungeon for a month.
I can change his name. That may or may not do any good depending on Google.
In order for it to change in their search index, they have to crawl the pages on this board. The less traffic a page gets, the less likely they are to crawl the pages anytime soon.
To highlight this problem...I get playboy girls who have a porn stage name but use their real names for their playboy and other mainstream work emailing us all the time. They're upset that people on this board are really a lot more intelligent than the common slug and put 2+2 together and want me to delete posts, edit them, etc, etc.
IF I actually do this, the info tends to stay around at least 6 months even though it's changed/deleted in our database. There's one chick who still can see the google results of her real name on our board and I deleted those posts well over a year and a half ago.
And people don't believe me when I tell them Google is the devil...
