Dynamic dns domains are used heavily by spammers as a free way to get new domains to spread links on social media sites (to evade domain bans). Typically these are fake dating site scams targeted at men. I’m dealing with this now at at one of the top social media companies.

This is not unique to duckdns. My own domains with completely innocent content get flagged as unsafe by the big gatekeepers. This is a growing problem for any of us outside their walls.

Wow, thanks for a reminder as to why I'd literally never use Facebook Messenger.

Somethings are actually indeed worth the friction-full conversations of "no, sorry please use (anything else) to chat with me".

Yeah, that's the only reason I'd heard of Duck DNS before - I got some "please sign in to your bank account" text with a link and I saw the domain in the URL was duckdns.org so I looked into it. With behavior like that on their domain, I'd imagine many browsers, firewalls, etc will block them.

My employer's firewall won't even let me access the site.
