Whenever one of these config items is updated, an `Update` activity will be sent to all know server to update your remote profile.
### Privacy replace
You can define domain to be rewrited to more "privacy friendly" alternatives, like [Invidious](https://invidious.io/)
or [Nitter](https://nitter.net/about).
To do so, just add as these extra config items, this is a sample config that rewrite URLs for Twitter, Youtube, Reddit and Medium:
```toml
[[privacy_replace]]
domain = "youtube.com"
replace_by ="yewtu.be"
[[privacy_replace]]
domain = "twitter.com"
replace_by = "nitter.net"
[[privacy_replace]]
domain = "medium.com"
replace_by = "scribe.rip"
[[privacy_replace]]
domain = "reddit.com"
replace_by = "teddit.net"
```
