I always set my Squidoo Guestbooks and Links Plexos to "contact me" first because some Lensmasters don't always read what should be posted there and what is not appropriate. This allows me to delete link entries without having to look at every lens every day to catch the junk.
However, recently I've had 2 types of annoying spam: (1) I was spammed in my Links Voting (Plexo). It was not a Lensmaster that I could tell, but in 1 day they hit 7 of my bear lenses with 4 links each to Fat burning sites.
(2) I was also getting spammed by a lensmaster doing the same thing on a couple of my cat lenses for something about intantcash. I know this was a Lensmaster because when I did properties on the link they posted, they screwed up and linked to http://www.squidoo.com/lensmaster/new_workshop/...
It was all happening at the same time so I'm pretty sure it was the same doofus!
What did I do? 1. I deleted all except the 4 entries on my Save Our Bears (SOB) Group -- which had 5 votes on each -- and reported it to Squidoo. This was so Squidoo could get the IP address or Lensmaster info. 2. I reported the spam to Squidoo through the Report Spam link. 3. They were able to block the user by IP address used on the link and warn the offending Lensmaster. 4. They removed the link from my sites as they addressed the issue.
So now you know what to do if it happens to you. Report it and help stop it from happening to others. The Squidoo folks are amazing and they eliminate spammers fast.
