For more info on the new rules at Squidoo, this is from a email they just sent to me: 

"Here are some important pages about SquidooSpam and Terms of Service policies .......  Please take a second to read them.

Hope it's helpful.

P.S.  They locked my article without warning.  Fortunately I had backed it up when I wrote it, but if you have any Squidoo articles not backed up, it might be a good idea to do it now.  Once they lock an article, it's gone.
