no delete blog comments

give examples of backlink generating comments with anchor text which have a lesser chance of getting deleted by the blog owner....
i intend to use them for generating comments via blog commenting software...

Your best bet is to find blogs which are unmoderated. Do this by looking at the backlink profile of other spammers.
