Ink - well - there's a thing.
They have either got to change to make the index "fresh" or get out of the business. I'd put it down to about 6-months maximum and it'll sort itself out. It's just got to the stage where the add url is "spammed out"
i'd recommend you build links from the pages that are in the index (I know they are getting re-visits) linking to your new sites. It won't do too much harm and may benefit your new sites.
Once in Ink, then we'll see if they stick. Importnat - if you do this, don'r resubmit with the add url. Be patient, watch the logs and wait.
report back any sitings of Ink spiders to new sites.
