Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

It's not as easy to defeat as just changing the pixel....

CSAM detection often uses existing features for image matching such as PhotoDNA by Microsoft. Similarly both Facebook and Google also have image matching algorithms and software that is used for CSAM detection which.

These are all hash based image matching tools used for broad feature sets such as reverse image search in bing, and are not defeated by simply changing a pixel. Or even redrawing parts of the whole image itself.

You're not just throwing an md5 or an sha at an images binary. It's much more nuanced and complex than that, otherwise hash based image matching would be essentially useless for anything of consequence.
