Well, I for one I did, and each time two identical invitations came at once. I won't accept them and I urge you to do the same (or drop the connexion if you've already had accepted them) (incidentally, each profile had already more than 500 direct connexions). My issues with these is that there was no other information besides what I've posted here, no public profile (obviously want to stay under the radar of public search engines) and for the two email domains other than Yahoo and Hotmail: cybergal.com and physicist.net they're just a couple of landing pages full of spammy link. I don't know why all of the sudden this new campaign of harvesting LinkedIn contacts (I wonder what these spammers do with them) but unfortunately it's not the first one and won't be the last one either. So, again, beware!

Hope this helps!
