As a Dutch and severely dyslexic writer, I have learned that there are two types of pointing out an error on the interwebs.
One, cares about the content, spots a mistake, politely and discreetly informs the author.
The other, points at the error in full snark, does a spiteful little dance of superiority, loudly announces it to the universe, uses that small error to dismiss the entire content and belittle the author while snorting their own farts.
The difference is intent, if it's genuinely to be helpful, then by all means, reach out if you spot an error in any of my writing. I can be blind to them, so that genuinely helps me. But if you're simply looking for a reason to feel superior, kindly, piss off.
