Just be sure to get all of it. It's pretty common that people leave a few pixels. How not to do it: https://imgur.com/ZaCIY5P

Leave generous margins. JPEGs can have compression artifacts that leak information outside the boundaries of the object.

It shouldn't matter if the original image (the screenshot) didn't contain any information to leak.

Thanks for making me look deeper into what's going on with common blurring algorithms. My instincts were clearly wrong here, for years I thought reversing blurs wasn't feasible in practice. I was very, very wrong.

Unknown Partial Knowledge is a huge problem in human cognition. This blew my mind, https://www.youtube.com/watch?v=tyHBnT4PmTE

This is less surprising to me than the gaussian reversal, because this motion-deblurring technique relies on several images of the same object. It's still cool, though :)

Your pedophile / homosexual comparison seems to imply there's such a thing as consensual sex with a child?? A pedophile is much more likely to molest a child, because that's the only way their desires can be realized in the physical world. A homosexual could, I dunno, go have consensual gay sex? That's why people find this comparison offensive.

I think the distinction is between what a pedophile finds themselves drawn to and what they do. And, I might add, there are many ways for people to find gratification without actually having sex, or in fact ethically needing the consent of anyone. Also, pedophiles are absolutely comparable to homosexuals—both are individuals classified for their sexuality, regardless of how they express it or wish to be classified. (…

Similar to how downloading some else's bank account into yours is practically thought-crime? "But officer, I was only shuffling bits!" isn't a defense.

I don't see how robbing someones bank account is comparable to downloading outlawed pornography.

Hoarding illegal material is a crime (and not a thought crime.) We call it 'recel' in French. Not sure what is the legal term in English, 'fencing' is argotic, right?

> To clarify, I absolutely to not condone any interactions whatsoever to do with pedophilia... but come on, people, let's not be blind here to the existence of people with full self control, ethical behavior, and private thoughts and desires.

Completely agree. Sad to think that there are people out there that have done nothing wrong, and cannot control their desires, and yet people (like many in this thread) would judge them without a second thought.

Lets hope none of them commit adultery by simply desiring another person. /s

They are both people with no relation to whether or not they will molest someone else they are attracted to. You could also just throw heterosexuals in there to be safe. I suppose if you wanted to avoid comparing a sexual orientation to something that isn't you could maybe use something like being attracted to people who wear glasses. People who find other people who wear glasses attractive has no relation to whether…

I'm with you 100% on the whole issue, and believe that pedophilia isn't any less ethical than homosexuality is, but I do feel that a sexually repressed person who cannot release their sexual urges is more likely to rape someone than a person who regularly has sex/relationships/etc, regardless of sexual preference. Maybe not very much more likely, but it's definitely not less, and probably not equal.

> but I do feel that a sexually repressed person who cannot release their sexual urges is more likely to rape someone than a person who regularly has sex/relationships/etc, regardless of sexual preference.

Agreed. Sadly, society (like many in this thread) would rather create an environment where people like that cannot get help. Rather, they must stay repressed, stay isolated, and further the likely hood of uncontrollable behavior.

Rehabilitation is something most don't want to discuss these days. God help those who lose the genetic lottery.

Possessing illegal bits is kind of a basic example of thought crime.

Someone who is homosexual isn't any more inclined to molest or rape someone of their own sex than a pedophile is to molest or rape a child. More on topic about censoring important information. I'm not entirely sure about this, but I feel like I've seen images where the thumbnail was retained from a previous version. Even at 32x32 there might be some way to expand it and gather some kind of information from its pixela…

It never fails: You can always find some pedantic creepy internet weirdo to start tut-tutting "now, now, let's think of the poor pedophiles..."

So you'd rather judge them without action? How sad a situation this is.

Rather than creating an environment where someone with desires (that they cannot control, mind you) must hide and isolate themselves, rather than Getting help!

You realize that you're only making pedophiles more likely to harm children right? They need help, not damnation.
