My account is opted out of full-text search (which is the default setting for all blorbo.social accounts).
In theory, it means that people using the full-text search are less likely to find my skz rpf posts.
This is why I don't bother to obfuscate names (e.g. 5kz instead of skz), as people often do on other social media sites.
It's not foolproof, though, and I know that there's a small but non-zero risk of people finding my rpf posts when they don't want to.
I'm okay with that small level of risk.
