You Should Know
YSK - for all the things that can make your life easier!
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.
Rule 10- The majority of bots aren't allowed to participate here.

The biggest issue is that you're giving them your email address and then posting info online. If you use your main email and then post something inappropriate or private, someone could easily leak that info. Someone who posts nudes without their face for example. A malicious admin could easily try to blackmail you with that info. Is it going to happen? Probably not, but why risk it?
You don't need to provide an email address to sign up at most of the big instances. I think lemmy.world is the exception. Even your instance lemmy.ca does not require an email address.
If you really want to provide one, you could use a service that does email forwarding. Some examples are https://simplelogin.io (owned by Proton Mail), and Firefox Relay (Owned by Mozilla, makers of the Firefox browser). These both have free tiers. There is also https://duckduckgo.com/email/ from the people who make the privacy focused search engine DuckDuckGo. That one I believe gives you unlimited new randomised email addresses for free. Very low attachment size limit but great for something like Lemmy.
You're right that you don't have to on most large instances, and that you can make burner email accounts if you have to.
But this post was simply about telling people to be careful of smaller, less known instances. The links you provided are excellent ways to protect yourself, even outside of Lemmy.
