I don't want to receive invitations from LinkedIn LIONs:
A LION is defined as a LinkedIn Open Networker. Basically a LION is someone who will accept a connection request from everyone and anyone who sends them one.
LinkedIn LIONs like to mark themselves with their "LION" status:
LIONs are easy to identify, as they will often display this in their profile in a number of places including their name field, headline and summary section.
I'm assuming they do this to attract invitations from eachother. Is there a comparable label I can use to mark myself as the opposite, to repel invitations from LIONs? ("The opposite" meaning I don't want to hear from you unless you're interested in working together soon, or we've worked together in the past.)
