Plugin creates multiple automatic redirects to the same destination. e.g./2010/12/257/feed/ redirects to the page - (over 500 in one day from a bot)
It does always redirect to the same page /2010/12/the-same-page/ but instead of logging e.g. 500 redirects to the the first created re-direct - it creates a new redirect each time...
End result - hundreds of auto redirects to remove manually
This plugin is excellent in concept (the other WP 404 plugins are way behing in versatilty), but definitely needs several things fixed. I'm using it on 4 WP sites but am having second thoughts now and may just go to a 404 logger and manual rediects with htaccess. I really cannot donate until the bugs are ironed out.
