So many link shortners eventually shut down due to people trying to obfuscate illegal stuff. Have you had any issue yet with that?

Oh yes, of course! I had to remove links several times. Even around 2AM at night.

I received so many phishing reports from Vercel and Cloudflare and even the Italian government directly. It was really tough so I had to add Google's Safe Browsing API check to check for any phishing links. I wish I didn't have to but no phishing reports since then.
