I have a site ranking #1 & #2 on Google for various different keywords. But I accidentally forgot to shut off commenting on a lot of back pages. And the site has been spammed to death with comments, its over 81,000 comments on the whole site. If I use the "delete all comments" plugin to delete all those comments, will it have any negative impact on my site? This may be a stupid question but I just want to make sure its ok to delete them all in 1 shot. Thanks.
