Ok, here is the solution of your problems and concerns.
If I am right, you are concerned that if you do excessive editing in older posts in quick succession, the pings from your blog will be considered as spam. Correct?
If you are using Wordpress, use the
Maxblogpress Ping Optimizer plugin, to block pings from older posts while you edit them. It is completely customizable and have advanced ping settings for your blog.
Hope this will help you.
