After setting up my ASN, I received unsolicited emails from NTT and calls from Cogent. Fortunately I haven't gotten anything (or at least anything that I noticed) on LinkedIn.

Except you know, those of us who actually use LinkedIn for professional
contacts and all.  I don't mind connecting with people as long as I've
actually talked with you before on some professional level.

It does have some nice features for connecting on a business level, just
people are abusing the shit out of it.
