Have fun, be creative, network, but know that your Twitter, Facebook and LinkedIn contact e-mail addresses are governed by the Law of Contract.
When you send, invite or accept an invite on social media networking sites, an unequivocal offer and acceptance has taken place. The Latin term, Animus Contrahendi the express and implied intention to be bound by one’s offer and acceptance – has occurred.
You have agreed that your e-mail address may be used to send you mail, including unsolicited commercial mail. Of course you can THEN express a preference to OPT OUT. This Opt Out constitutes a revocation of your offer.
An agreement is made when an offer is accepted. By issuing an invite, you tender an offer. By accepting the invite the recipient has accepted your offer. This means you have both consented to the use of each other’s e-mail addresses.
