As noted by security researcher Will Dormann, some posts on X purport to lead to a legitimate website, but actually redirect somewhere else. In Dormann’s example, an advertisement posted by a verified X user claims to lead to forbes.com. When Dormann clicks the link, however, it takes him to a different link to open a Telegram channel that is, “helping individuals earn maximum profit in the crypto market,” he said. In short, the “Forbes” link leads to crypto spam
Honestly, ANY platform that obscures links through redirection should be considered unsafe. If you can’t verify the target URL before you click the link, then you are asking trouble. Twitter and similar platforms do this so they can track you more effectively. (In the past it also served the purpose of shortening links to SMS-friendly lengths, but that ship sailed like 10 years ago.)
Not that visibility automatically would make it safe, but it is the bare minimum required as a starting point.
