Anecdote, but I've never been able to use Claude (directly) because their defense systems seem overly sensitive to your email address. I signed up for Claude using a relatively new Outlook email address that I set up for an independent purpose. My account got instabanned. Like, I couldn't proceed at all. I don't even know what the Claude UI looks like. All I could do was appeal using a Google Form.

I appealed and got a standard Google Forms response. There was no follow-up after that. It never got fixed and I never tried again... plenty of free, more accessible fish out there, and various agents like Copilot give me access to Sonnet anyway.

But now I wonder, what is it about the account that triggered this block. If it was because of the reputation of the account, how did Anthropic even know that this account was created a few weeks ago?

There are vendors like Emailage that somehow determine the age of email addresses. Very useful because fraudsters tend to buy credit cards and bank accounts, then need to complete the identity by registering an email address for that identity.

Historically, outlook emails have been very easy for this compared to gmail addresses, which require phone numbers, etc.

One of the reasons "aged" account marketplaces got more popular. People buy from vendors that farm a ton of these accounts and wait to sell them, or those reselling compromised accounts (especially with EDU accounts before institutions actually implemented security controls).
