There’s really no good way - if you act normal they train on you, and if you act badly they train on you as an example of what to avoid.
My recommendation: Make sure its really hard for them to guess which you are so you hopefully end up in the wrong pile. Use slang they have a hard time pinning down, talk about controversial topics, avoid posting to places easily scraped and build spaces free from bot access. Use anonimity to make you hard to index. Anything you post publicly can be scraped sadly, but you can make it near unusable for AI models.
Not completely true. It just needs to be data that is organic enough. Good AI generated material is fine for reinforcement since it is still material (some) humans would be fine seeing. So more like: it needs to be human approved.
