There are many free tools available online to check wether a text was written using AI or not (with high accuracy) like this

Can you name some of these tools ? I searched online but most offerings appeared to be scam only.
There's a thread in the reputation board where you can report those who are using AI to make posts. Some of the tools they're using online are
Copyleaks, Hive, Sapling, ZeroGPT and GPTZero. It's useful for making sure that what you're reading is reliable. However, like any tool it's important to verify that it's not making errors itself.
You can report here if find someone using AI:
