Re: Which is why I always turn off email sigs...
In fact, if they decide to forward it as a BCC to the entire Gmail, Apple, AOL, Microsoft, & EU email owners as global spam, there's not a damned thing the sender can do to stop it.
Not strictly true. Forwarding an email in its entirity without permission could possibly be pursued as being a breach of copyright. (You own the copyright to any email you wrote yourself).
