Please forgive the lack of an LJ-cut, but I want to get everyone's attention.  I'm sure you know about this by now:

(Make sure you've read the article on LJ-news before you do anything else.)  In response to the new Pepsi advertisements, V-gifts, and logos all over the place, in VIOLATION of LJ's customer contracts, I say we take a stand, and hit Six Apart where it counts.

I just got off the phone with Pepsi Customer Relations.  I told them, very politely, with utmost concern for their corporate image, that their logo is being used in advertisements by Six Apart on Livejournal Paid Accounts, in violation of customer contracts.  I explained how the good corporate image of Pepsi could be tarnished by their sponsorship of Six Apart.  I let them know that we, the customer base of Livejournal, are infuriated at Six Apart.  We're going to stop drinking Pepsi and purchasing Pepsi products.  We're going to avoid anything sponsored by Pepsi.  We're going to tell our local restaurants and retailers to stop carrying Pepsi.

I told the Pepsi representative that we're going to tell our friends.  And there are a LOT of us.  I used the estimate of 30,000 irritated fans, going by the number we got from Fandom Counts.  I hope you think that's a fair number for me to use.

Here's what I'm asking you to do:

CALL PEPSI.  Tell them what's happening with Six Apart.  Explain that 6A is violating customer contracts by placing advertisements in paid accounts.  Tell them that it will look bad for Pepsi, and that Pepsi should withdraw their corporate sponsorship for their own good.

I didn't call the customer service line directly because I couldn't find it at first, but I got connected through the vendor's number.  I think THIS is the Customer Service line: +1(800)433-2652
Or the basic phone number for the headquarters:  +1(914)253-2000 That should connect you to anybody at the Headquarters, and I'd recommend this number most.
