What is the general quality you get from that approach? Taken from my experience: When posting to for example 1000 blogs the batch cools while your link gets further and further down the list. Link checking the first 10 minutes can give you a high yield but after a day only a few % remains. The links that stick is the links that count. Are you with me? From the above example what can you tell me. Good, Bad, Filtering, Picking, Limiting, Checking.
