Hi there, our team is aware of ongoing reports of spam and continuing to actively implement new ways to improve spam filters and submissions. However we always recommend implementing additional ways to deter spam using your own filters or methods.
i.e.
- Enabling ReCAPTCHA (which it seems you’re doing)
- Adding honeypots (i.e. adding hidden fields that only bots would be able to fill out)
- Adding skill questions or user authentication
- Or for additional protections, enabling anti-spam plug-ins & services
