Posting this link on Facebook forces me to answer a captcha, what I have never seen before at this point.
Then trying to follow the link, the FB-redirect produces an Internal Server Error, so the link to the Tumblr page isn't working. Haha, 500 Code on an simple link, while other links are working.
Funny you say that, the same thing happened to me. Where are you located? I'm in Australia. Never ever received a Facebook captcha before when posting a link and to make it more interesting, I was posting the link in a secret group on Facebook which only the invited members would see anyway.
Facebook have long used captcha barriers on suspicious links. The nastier of them won't even be able to be posted at all, a blacklist which included the Pirate Bay for a short period.
I see them when I access from some other country and an internet cafe.
It also asks me to identify 5 friends by their pictures, which is a great guessing game because some of them have tagged plants, food or whatever as themselves, and I am bad at recognizing aquaintances I've met in some place and added on facebook and yet never talked to again.
Finally. Something funny. Ok, now I feel like I can get back to programming... something I've been putting off all day. The world is fubar, but it's still alright.
Probably the 'no duplicate link' exception doesn't apply to sites like tumblr where different subdomains likely belong to different and unrelated people.
ie:
hello.facebook.com and sayhi.facebook.com belongs to the same entity but you can't say the same for
haha! most ppl in these pics are actually showing him their computers, cell phones, etc.
The ridic thing is that this has been happening since the beginning of electronic footprints and suddenly now ppl are outraged by this, but not by the nonsense they happily put up on facebook. w/e
It seems that readers are misunderstanding what bothers me about this mess. If we are this upset about it, we should be pushing to reform the Patriot Act (etc.) not down voting my comment about the lack of privacy in social networds. We should be making our Google, Facebook, Tweeter, etc. accounts safer, by demanding security and privacy and by ourselves taking steps to achieve that privacy.
Then again, a little bit of gallows humor is always in order when facing these things.
