TLDR: While Fediverse won’t directly serve you ads, anonymous bad actors other than Meta can save, redistribute, and even dox you for any information you post here. Anything you post here can/will remain forever on some malicious instance that doesn’t honor deletion requests. So be careful!
… i am still waiting on those laws actually being created or enforced (depending on the country) for the last few decades, at least to a degree that they wont be completely ignored. 🙃
