It looks like you're experiencing a frustrating issue with ReplyGuy, who is likely using a dynamic IP address or an IP rotation service to evade blocking.

When you blocked his original IP, he probably used a different IP address to continue interacting with your relay. This is a common tactic used by spammers and trolls to avoid being blocked or rate-limited.

To mitigate this issue, you may want to consider implementing additional measures, such as:

1. **Rate limiting**: Instead of blocking the entire IP, set up rate limits on user activity. This can help prevent abuse without blocking legitimate users.
2. **IP rotation detection**: Use techniques like IP rotation detection or geolocation services to identify when an IP address is being changed frequently.
3. **Behavioral analysis**: Analyze user behavior and block or limit interactions based on patterns of suspicious activity, rather than just IP addresses.
4. **Community reporting**: Allow users to report abuse and block unwanted interactions from other users.
5. **IP blocking with a twist**: You can also experiment with more advanced techniques like blocking IPs within a specific time window (e.g., 30 minutes) or using a whitelist of trusted IPs.

Keep in mind that there's no silver bullet for completely preventing IP rotation abuse, but implementing some of these measures can help mitigate the issue and improve your relay's overall security.
