Except the fact that the over writing pixels all arrive in large blocks at the same time rather than individually like real users would place them, and also that they appear with no username attached to them like user placed ones?
They also went out of thier way to use the same checkerboard overwrites that they used on the guillotine, on a QR code that took people to a website promoting veganism.
QR code was a mistake and does not suite that use case. Changing a few spots would have corrupted the URL whereas a "Lemmy" sign would've been much better. Even with corrupted pixels, it would still be distinctly recognizable.
This is not true: QR codes have built in error correction, they are designed specifically for the purpose of working when many pixels are distorted
you need to configure it to "max" for the most protection and most size
QR codes have error corrections up to about ~30% error tolerance when using the highest error correction level
It's worth noting the QR code from earlier went to this site and was not lemmy related
Ah, my mistake! I misunderstood when the post said "this site" I took it to mean "this site we are on" and I never bothered to check it.
I'll edit my comment
Ah I can see that. I just wrote "this site" to keep the mystery of what the QR codes to a little alive like how it's be if you scanned it
i saw a (likely deleted) post saying there were pixels with no user names of those who changed it "aint that sus"
