I have had a couple of lenses locked previously and to be honest I don't think I had much to complain about as there was some duplicate content lifted from Amazon and the lenses existed purely to sell a product with my Amazon affiliate links. I figured there was no real way back for these so I just deleted them.
However, I have more recently had another lens blocked that contains entirely original content and is not promotional - it does contain three Amazon affiliate links to books related to the subject, but this is entirely within the rules. It also contains Squidoo's Ebay module. It contain a dead link which is what I am guessing tripped off Squidoo systems. This was to a Clickbank product which no longer exists - this was one single link at the end of the lens. I have now removed this link.
I have e-mailed the folks at Squidoo a while ago now and have had no response. This is very frustrating as if there is no response within 60 days then the lens will just be deleted from Squidoo. This is all rather ironic as this is probably the most original of my lenses and I really put it together to be useful to other people rather than to make any money. It is the lens that has had the most comments and positive feedback and one of my most visited lenses. Ultimately if I get no response then I will have to export my content elsewhere.
This has dented my faith in Squidoo somewhat, but has reinforced for me the need to focus on my own websites rather than relying on making money from posting content on someone else's.
