Hm, that's an interesting error. Judging by the undefined indices, I'd be inclined to think that it's possible you forgot to select a file, and/or something glitched with the captcha.
Either way, I like the facebook spider test idea. Though, I would think that their spider shouldn't trigger the download, because the way it's set up is each "download link" is just a page with the real download link on it, which submits a form that does all the processing to figure out if the file should be deleted.
I've also been having problems with the files actually staying until the set number of downloads, but it's something I'm working on. Thanks!
This is the critical information that these articles never mention. It's always "We emailed a few friends and the next morning we had $100 billion in VC funding and a private island!"
I wish more blogs would include the "luck" details in their success posts. It's practically lying to say that all that happened was that you tweeted to ~100 followers. I'm not trying to criticize, it's just an interesting bit that makes the startup sound much more down-to-earth when they're willing to admit where they got their luck from.
Because let's not forget: all success is due to some luck, and that's sometimes the most interesting part of the story.
I took a class that was very writing-intensive. I was one of the only people to ever actually change the font in my essays from Calibri to Times New Roman, and always wondered if this contributed to the fact that I did substantially better than most other people with very comparable essays.
An interesting bug, but if anything won't it just earn you fake points on a website, while making everyone on that website hate the account that's accruing the points, essentially making those "hacked" points' meaning moot anyway?
