The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rule 1- All posts must begin with YSK.
All posts must begin with YSK. If you're a Mastodon user, then include YSK after @youshouldknow. This is a community to share tips and tricks that will help you improve your life.
Rule 2- Your post body text must include the reason "Why" YSK:

Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-YSK posts.
Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you harass or discriminate against any individual member, you will be removed.
If you are a member, sympathizer or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people and you were provably vocal about your hate, then you will be banned on sight.

Rule 8- All comments should try to stay relevant to their parent content.

Edit: obligatory explanation (thanks mods for squaring me away)...
What you see via the UI isn't "all that exists". Unlike Reddit, where everything is a black box, there are a lot more eyeballs who can see "under the hood". Any instance admin, proper or rogue, gets a ton of information that users won't normally see. The attached example demonstrates that while users will only see upvote/downvote tallies, admins can see who actually performed those actions.
Edit: Obligatory RIP my inbox.
There are a number of things you can do, depending on how serious you want to get about it (think about who and what you want to protect against - harassment from other users? Admins?).
Create an account using an email alias or an email account not linked with something you can trace back to your real identity.
If you're concerned about retaliation/harassment from downvoting something, you could create 2 accounts - one for normal use and the other you only use for downvoting, or one for participating in discussions on controversial topics.
You could retire an account and start using a new one after a period of time, so your entire history isn't linked to a single account.
The above might be able to shield you from other users but not from admins.
If you want to stay anonymous from admins:
An admin would be able to see the IP address the account uses to connect to the service. If 2 accounts connect with the same IP address and the IP is consistently the same, they'd be able to conclude it's likely the same person (or someone else in their household) is connecting to the service with both accounts.
If you use a VPN or Tor when connecting to the site, that won't be as easy to see because many people would connect to the service from the same IP address and the account would likely frequently connect using different IP addresses.
Be aware that if you access the site on a mobile device app with a VPN, it's possible that the app could contact the server when the VPN is down (for example, if the VPN connection is closed when the device is locked). To avoid that, you could try using using something like OpenVPN with its "Kill Switch" enabled).
Note that the admin of the VPN service would be able to see your connections to Lemmy's servers (but not specially what you're doing on Lemmy), so you aren't fully anonymous. Lemmy's admins would see part of the picture, the VPN's admins would see another part, and you're counting on the 2 not talking to each other (and a good VPN service shouldn't, unless they're legally required to).
I use a VPN in general for all connections to the Internet but don't always care to keep my IP address hidden from some services (banking, primary email addresses, etc - services that will have my personal info anyway). It can be very challenging to keep your IP address hidden over the long haul with a frequently used service - you could end up connecting with the VPN down due to a technical reason or carelessness.
With some services I might have multiple accounts - on one I might not really care if my real IP is revealed, but another on the same service that I'm very careful with to keep hidden.
You could use a browser with protections against fingerprinting like Tor or Mullvad Browser.
