Hatefully aggressive "social networking."

Bitten by social engineering.
So I got an email from someone I had never heard of, on an email I had never heard of, telling me that this someone had bought me a "virtual drink." Thinking it was spam, I told it to go away.
I received another email telling me that my drink was about to expire, and "Ellie" would be upset if I didn't accept it. I know so many names across the internet, hell, maybe I did know the person. I clicked on the link "See Ellie's Profile."
What I got was a very busy site that looked like a profile page, but it was lightboxed out with a pop-up saying, "Too see someone else's profile, you must have a profile of your own," and your typical "Tell us your username, password, etc." form. "Screw that," I said, and closed the window.
The site proceeded to bomb me with emails about people who had seen "my" profile, or given "me" more virtual alcohol, or whatever bullshit. The only way to stop the torrent was to actually finish the profile, then demand it be deleted. The question it asked was "Why? Not enough hot people? Or some other reason?" with a box for the other reason. I left a nastygram, for all the good it'll do.
Grief, I hate sites like that.

Meh, regexes are too much work.
Date: 2010-10-17 02:11 pm (UTC)1) Use greylisting, preferably with OpenBSD's spamd (Some of the variants for postfix have been less than effective). The botnets still don't bother attempting to resend because 99.999% of their targets are on systems that don't greylist.
2) Use email addresses that exercise a bit more of RFC 2821. mailbox+folder@[subsubdomain.]subdomain.domain.tld works wonders. Enough spammers strip the subdomains and see the +folder as invalid. And mutate folder and subdomains regularly for new clients, new vendors, and new bug reports.
3) Make use of spamtrapping. Post regularly to USENET with a client that creates predictable message-IDs for your domain, have those patterns configured as bad for tools like 'greyscanner'. When an email address given to a vendor is compromised have a chat with the vendor and add that email address to the spamtrap list.
4) Make use of tarpitting, If a sender is on a blacklist, let them spin on an SMTP connection that will ultimately reject them with a temporary failure.
Then again, I'm *ALSO* the sort of anal retentive to put the old 56K modem on the landline and set up mgetty to answer the phone when caller id is blocked, or the number has been confirmed to be a telemarketer. I'm just disappointed that none of them have attempted to call back with a modem because I'd love to apply computer trespass laws against them.
