Patched bp-core-adminbar.php with:

if ( bp_blog_signup_enabled() ) {

echo '<li' . $alt . '>';

echo '<a href="' . $bp->loggedin_user->domain . $bp->blogs->slug . '/create-a-blog">' . __('Create a Blog!', 'buddypress') . '</a>';

echo '</li>';

}

line 171-176

With “Only user account can be created” enabled.

“Create a blog” still appears in admin bar and on member page.

Tested as user without any posting permissions; blog contributor; admin.
