At SOURCE Boston, Jeremiah, Mark Kranack and I were sitting around talking and apparently at one point long ago he had started a religion. The religion was simple, all you had to do was accept Mark as your god and that’s that. No fees, no prayers, no nothing, just accept him as your god. You don’t even have to do it on purpose, one guy joined by accident as a matter of fact by inadvertantly saying that Mark was his god as he described it. There’s no way to get kicked out of his religion and nothing really special about it in any way beyond the religious leader, of course. You can still find a reference to it on [the internet archive](http://web.archive.org/web/19990826095540/http://www.access.digex.net/~mkraynak/). Then we got to talking and laughing and ultimately came up with a CSRF joke of all time. We could get tens of thousands, maybe hundreds of thousands, or even millions of people to join through CSRF via images to forms on MySpace, or what have you. You see, there is a bit of a bug in the acceptance program of Kraynackism. You don’t have to necessarily “say” that Mark is your God it turns out, you just have to somehow indicate it to him, either intentionally or inadvertantly as we saw with his friend. We could turn Kraynackism into the fastest growing religion the world has ever seen! You could be a member right now and you wouldn’t even know it! It’s funny but it’s less funny when you talk about getting people [arrested in China](http://itgossips.com/featured/open-a-page-go-to-jail-2-735.it) as we talked about [a long time ago](http://ha.ckers.org/blog/20060614/using-xss-to-dos-china/) or of course [going to jail for child porn](http://ha.ckers.org/blog/20080320/click-a-link-go-to-jail/), etc… Funny and scary all at the same time. ## Recovery notes Source evidence recovered on 2026-09-14. The earlier source capture (SHA-256 `c8b339658ea84b63bee6671e8ce29f18640ec11cb43d193e0eb970b48b404861`) is no longer available. This publication uses a separately preserved capture of the same document recorded on 2026-08-06 (SHA-256 `b05a554e2185cb4180dd8b33399aecdc0d0b5146c5599c5f56ede90fb839cb2c`). The retained article text was checked against this replacement capture. Full retained CSRF example and surrounding account agree, including image-to-form triggers and unintended acceptance. Existing capture-quality limitations remain recorded separately. The missing earlier capture remains documented in the archive history.
