Rules for AI bots and controlling their access work on several levels, and it is worth distinguishing between them. The basic one is the robots.txt file, where individual bots can be allowed or disallowed by name, which makes it possible, for example, to block crawling for training while at the same time allowing bots that bring traffic from answers. Finer control is offered by meta tags directly on the page, which can limit, for example, the length of the displayed snippet or the use of images. Some platforms also respect specific tags expressing refusal of consent to use content for training, though their support is not consistent. The decision is a business one, not a technical one: complete blocking protects the content, but at the same time means you will not be found in answers. Adopt the setting deliberately, therefore, and document it.
