Many AI companies now offer opt-outs from training. But how well do they actually work, and what are the catches?
By default, most scraped web content is fair game for AI training unless you actively opt out. This is the opposite of GDPR's consent model. The ethics are debated, but the technical reality means individuals must proactively block usage rather than grant it.
| Channel | Blocks what | Effectiveness |
|---|---|---|
| robots.txt + GPTBot | OpenAI's crawler | Works for OpenAI |
| robots.txt + ClaudeBot | Anthropic's crawler | Works for Anthropic |
| ai.txt (proposed) | AI training specifically | Voluntary, patchy adoption |
| DoNotTrain meta tag | Sites that honor it | Limited |
| OpenAI individual opt-out form | Future training | Only OpenAI, does not affect already-trained models |
| Spawning.ai's Have I Been Trained | Future LAION, Stability | Depends on compliance |

Disallow: /A robots.txt blocking major AI crawlersIf your content was scraped and trained on before you opted out, the model already knows it. Most labs say they cannot cleanly remove individual training data from a trained model. At best, they promise not to use it in future runs. This is the most common complaint from artists, writers, and content creators.
The big idea: opt-out mechanisms exist but are patchy, retroactive only by promise, and depend on good-faith crawlers. Real consent requires a different default.
