I'm pretty new, anything I should know?

[Nova.]

Security question: My IP is completely invisible to everyone, including mods, right? I use a VPN, just in case my IP does get leaked. I don't wanna get doxxed.

I am just afraid of information breaches.

I'm gonna assume my IP is invisible to even the owner of the site. Thanks to all who gave advice!

Your IP is visible to mod+. This shouldn't be a worry because IPs are only tied to a general location and can't be used for actual harm. IP leaks should be the least of your worries.
