WARNING: Phishing Attacks, HTML markup to hide urls, are now in Mastodon.

While Mastodon does not have markup to allow hiding urls, they share API with "friendica" and friendica ALLOW HIDING URLS.

And friendica accounts can post on Mastodon.
I have asked for a solution, none is forthcoming.

Click NO LINKS that come friendica. Be wary of links on Mastodon, as if Mastodon were "email" - without any protections.

Multiple reports of other fediverse branches allow hiding urls. No Clicking links

@Kevin Russell I know what fishing is. I know what a link shortener is. That is not what is used here. To see the full url, most clients let you do that by long pressing. This is neither shady nor what you call hidden. It's a feature that most software outside Mastodon uses.
Friendica is not a bad actor. Neither is Akkoma, Calckey, Hubzilla and the others. So no need to worry.

@shimriez

Mastodon needs to reveal full links in plain text when they are hidden.
