For example I got 1000 high PR pages for commenting from site blackhatword.com etc. I only want to post not more 10 different pages each time, the reason is first I don't think too many a time to a site would be good to SE, second if you post 1000 to a site shortly , maybe the webmaster will not even let one of your commenting shown on their blogs? And surely I can't do it manually since too many sites or I can't use the remove duplicate function because I don't want to post only one out of 1000 pages. any idea on this? Or my worry is too much?
