A safest practice is don't check link, don't click on link from strangers. You don't have to mind about links sent to you by strangers and don't need to waste your time for checking whether those links are safe.
Practically speaking, is there a way you can be on the internet without clicking links entirely? I don't think so. I mean, the OP posted links, and you also posted links, so if I don't click on the links posted, I won't learn about what the link contains.
I receive emails that require me to click links from streaming services, work related and other stuff, so personally speaking, I don't see how I can avoid clicking links entirely. All I can do is try not to click links that look suspicious. I know it's a flawed way, but I can't decide not to click links.
I'm super careful about the source of where it came from and other stuff because I know hackers can pretend to be something else and send me an email.
The good thing is emails from unverified sources usually go to "spam" but I'm still careful nonetheless.
