Today, misinformation on social media has become way more harder to control. In the past, misinformation might looked like very fake or strange. It can be a short video, an edited photo or a real video posted with the wrong description, and platforms like Instagram and X can make information like this spread very quickly, so I wanted to look at what these two platforms are currently doing to fight misinformation.

Instagram

For many years, Meta worked with professional third-party fact-checking organizations. These organizations reviewed questionable posts, and Meta could add warning labels or reduce how many people saw false information.

However, Meta made a major change in 2025. It ended its third party fact checking program and began replacing it with Community Notes. Starting in April 2025, Community Notes began appearing on Facebook and Instagram. Instead of professional fact-checkers deciding whether something needs more context, users can write notes and rate notes written by other people.

Instagram also uses labels for AI generated content. Meta says it can add an “AI info” label when its systems detect signs that an image was created by AI or when a user says that AI was used. Meta can also use stronger labels when manipulated content has a high risk of misleading the public. Content can still be removed if it breaks other rules, such as rules about violence or harassment.

I think AI labels are useful because AI images are becoming much more realistic. A person scrolling quickly through Instagram may only look at an image for a few seconds. So without a label, they may never stop and ask whether the image is real.

However, I think this system has a problem. Community Notes depend on people noticing a misleading post, writing a note, and then other people can rate that note. All of this takes time, a post can receive thousands or even millions of views before a note appears.

My suggestion would be to use both systems instead of choosing only one. Instagram could continue using Community Notes for normal posts, but professional fact-checkers could review posts that are spreading extremely fast or involve important public events. Instagram could also temporarily slow down the recommendation of a suspicious viral post while it is being reviewed.

X

X has used Community Notes longer than Instagram, and Meta’s system was partly inspired by X. On X, contributors can add notes to posts that may be misleading. Other contributors then rate whether those notes are helpful.

One interesting part of the system is that X does not simply look for a majority vote. It tries to find agreement between contributors who have disagreed with each other in the past. I think this is a smart idea. If people with different viewpoints can agree that a note provides useful information, the note may be more trustworthy than one supported only by people who already agree with each other.

Another feature that I think makes X different from Instagram is Ask Grok.

Grok is X’s AI , users can tap the Grok icon on a post and ask Grok for more information about what they are seeing. Grok can give people analysis, or background information about a specific post. Grok can also search public posts and real time web information, which I actually think this can be very useful for misinformation. This is different from Community Notes because I do not have to wait for someone else to write a note, I can just ask for it by myself.

However, Grok also creates a new problem.

X’s own help page warns that Grok may sometimes give factually incorrect information, summarize something incorrectly, or miss important context. This is important because an AI fact checking another social media post does not automatically make the answer true.

For this reason, I see Grok more as a research tool than a fact checker. If I see a questionable post, Grok can help me understand the topic and find more information. But I would still want to check reliable news organizations or original sources before deciding that something is true.

But I think the biggest problem for X is also speed.

A misleading post can receive thousands or millions of views very quickly. Even if Community Notes eventually adds the correct context, many people may already have seen the post.This is why I think X should connect Grok and Community Notes more closely.

For example, when a post is spreading unusually fast and many users are asking Grok whether it is true, that could be a signal that the post needs faster review from the system. X could also show a simple message such as “More context is being reviewed.” This does not mean X has to say the post is false. It would simply remind users that there are questions about the information and that they may want to check other sources before reposting it.

Which Approach Works Better?

I do not think either Instagram or X has solved the misinformation problem. Community Notes have an important advantage because they allow regular people with different viewpoints to participate. They can also add context without automatically deleting someone’s post.

I also like X’s Ask Grok feature because it gives users more control. Instead of waiting for the platform to tell me that something may be misleading, I can actively ask questions. However, these systems depend heavily on users. A person has to care enough to read the Community Note, click Ask Grok, or search for more information.

The problem is that social media is designed to move quickly. Many people see something surprising and immediately share it, that can happen much faster than fact checking.
