already parsed ?

I am getting lot of already parsed . that mean if its found duplicated domain or url ?
if i am using blog comment and if i need to post same domain many post . but why its getting already parsed. any option to block it?

As titel said its already parsed.  But if you use dropbox to sync ( instead of importing .sl) it may false alrm as everytime dropbox syncs it got cache. So you can simply ignore unless you use a .sl file. If then it really means it)/

you can delete cache as well
