The passports stamps along with the itineraries matching the date should be fine. If you still have boarding passes, that's even better than the itineraries They are probably looking for the passport stamps.
Do you have any receipts from the trips? Cash machines, hotels, anything like that? All of these are better than time stamped photos. I sent in photos and only wrote the names, locations, and dates on the back of those photos and they were okay. But I also included the passport stamps and itineraries. Only some of the boarding passes because I didn't have them all.
Remember, you only need to prove with primary evidence that you've met over the past two years. The pictures are considered secondary evidence.
It also sounds like they are asking for a statement from you of how you and your fiance met. Online? Through friends? At school? Whatever, just a statement about how and when you met and started dating.
EDIT: I see Lynkali posted while I was typing, and said pretty much the same thing

This is how civil wars are started
Both centers suck. The system is broken.

Long distance relationships suck. She was probably hoping you would rush to be with her once you were finally approved, and is disappinted that you don't want to do that. Talk to her. You two will work this out.

My RFE deadline was just shy of 90 days from the RFE date.
You can not fax or email. Only snail mail. I used USPS Express mail as it is an overnight service that delivers to PO Boxes.

Congratulations! I think I'm going to go drop some pennies in the toilet now

I'm hoping they approve some more of us April RFE people this week!

Just my 2 cents.
Your goals are admirable and you are confident that your methods are legal and that no personal information can be extrapolated from the data you collected.
The failure in your goal of this data reaching as many people as possible was in your approach. You came into a public forum masked with the name "Tyler Durden", addressing you and your posse as "we" with creepy little catch phrases and a somewhat arrogant attitude. You created a public poll and sought out the needless opinions of as many people as possible. You rushed to get your data out as soon as someone objected to it. You produced a video declaring your message in a manner in which most people would not relate to.
You were essentially standing in the middle of a room, waving your arms in the air, wearing a mask, and shouting "Look at me! Look at me! I have the power to change your life". It was too much hype.
Had "Tyler Durden" come onto VJ as "John Smith", posted the data and said "Hey guys, look at what I found" you would have attained your goal of reaching as many people on here as possible. I assume the first thing someone would have done was look up their own number to verify the validity of the data. They may have then checked more against the USCIS website. Word would have quickly spread. People would have worked their magic and a few days later charts and graphs would have been plastered all over VJ encouraging discussion and debate of any possible observations and conclusions. These conclusions may have then been passed on to elected representatives. This outcome would have been more in line with your overall goals.
I personally am very interested in what you are doing and think the discussions could have been both meaningful and beneficial to many, including myself. As you are well aware, VJ members account for between 5-10% of the total I-129F population. I'm sure you could provide me with the exact number. I am doubtful that you could have found a higher concentration of people interested in what you have to offer on any other website. But you blew it. I think your arrogance prevented you from attaining your goals.
My suggestion to you is the next time you take on an "Anonymous" project, try to be a bit more anonymous. It could been everything you wanted.
