Deleting Blogs Leaves %user-name% in URL

It's not just blogs, it's on several things. But when I remove a blog and ban the user, I get a URL that has "%user_name%" in it. Is this something configurable or am I missing something?

While most of these were deleted spam-blogs ... some of them were not and I would like to find a way to make certain that these visitors will hit a page and not a browser error page. I'm thinking that the browser can't parse out the "%" in the url string. ???

Anyhow, the rewrite is changing this: mysite.com/forum/entry.php?b=1461

Into something like this: mysite.com/forum/blogs/%user_name%/a-/

Hello,

please try to modify functions_vbseo_createurl.php file:
find:
$returl = VBSEO_URL_BLOG_DOMAIN . $returl;
add below:
if(strstr($returl, '%'))return '';
