The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
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:
**In your post's text body, you must include the reason "Why" YSK: It’s helpful for readability, and informs readers about the importance of the content.
**
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.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.

So if one downvotes something and then removes that vote, does doing that removes it saying they downvoted or does it still keep it on record?
I had to run an experiment on this one.
It appears that changing you vote causes the old vote to be completely deleted from the database and a new vote cast and propagated.
Edit: The above description is what happens in the COMMENT_LIKE or POST_LIKE table HOWEVER the ACTIVITY table reflects both actions, which makes sense since it's a complete transaction log. So, it's a slightly more complex query but the history is maintained.
However, that's not really any better for privacy. There's absolutely nothing preventing someone from logging a history of the changes.
Upon further experimentation, the ACTIVITY table maintains both transactions so... there you have it.
Depends on the rest of the structure of those tables and the supporting procedures that modify them. I haven't checked, but I'm very interested in using this as a sample dataset.
Weird way to say you don't know.
I guess, but it's less "I don't know" and more "it's not knowable" from the screenshot alone. We need to see more of the schema to answer the question. "I don't know" fails to communicate what would be needed to answer the question, it's an okay answer, but I think mine is more useful.
It is knowable. You just don’t know it.
Yes, that is what I said.
