Not American. You misunderstand the concept of "personal".
Edit: also it doesn't really matter if you are in the US (or where you are at all). If you deal with European customers (their data) you have to obey GDPR. That's why some sites have opted to simply block European visitors.
Yes. Preferably something the LLM people can't easily identify as garbage. Make your data less valuable.
Yes strong protection will make me cry so hard.
If my reddit comments are helping troubleshoot something technical and unrelated to me, that still isn't personal data. Valuable comments will be available on reddit and generating them traffic from Google searches regardless of how much people here scream about GDPR.
Is it really a GDPR violation if no article 17 request was sent AND those comments contain no PII? PII is the key for GDPR, your "IP"/contribution to Reddit means nothing
Yes, if the comments contain PII after your article 17 request Reddit would be in violation
Not necessarily deletion, anonymization would free your info from any GDPR requirements and Reddit couldn't care less if your username is there or not
You mean don't be evil? They removed it in 2018
Whatever makes you feel better. Keep screaming GDPR at everything...
