An uptick of bots signing up

Yes, same here on some of my client’s sites.The new blocklist is excellent.

I plugged in chatGPT to verify the e-mail of new users, and integrated with Make. If the e-mail is classified as spam, the user is deleted.

Here’s the prompt, it returns a JSON with SPAM or VALID.

Analyze the provided email address and classify it as either SPAM or VALID based on the following criteria:

If the email address contains only numeric characters in the local part (before the @), classify it as SPAM.

If the domain is associated with disposable email services or SMS-to-email gateways (e.g., tmomail.net, txt.att.net), classify it as SPAM.
Otherwise, classify it as VALID.

Respond with the classification in JSON format withouth any markup or formatting using the following structure:

{
  "email": "example@domain.com",
  "classification": "SPAM or VALID"
}

Example Input:
6562048787@tmomail.net

Example Output:
{
  "email": "6562048787@tmomail.net",
  "classification": "SPAM"
}

This scenario triggers on Ghost New Member and sends a Welcome e-mail if VALID and deletes the member if SPAM. Also sends notification to site owner.
