I've gotten quite a bit more unsolicited vendor contact which I can almost surely pinpoint to linkedin.
Aggressive sales folk have figured out most companies email addresses are first letter of first name, last name.
If yours fits in under the normal kerberos/(open)LDAP limitations.. yep, you can ascertain my work email.
I usually get a few a day, and digging through to the HTML link to unsubscribe seems to do nothing to fight
the overwhelming wave of incoming bothers. Most of these solicitations seem to be auto-scraped and generated,
for example any simple review of my profile would see I'm not interested in Microsoft solutions.. or they are not relevant
to my job function, seemingly to only generated by a keyword or two.
