valid XSS being rejected

[doesnotcompute]

Hi

Could you clarify why these submissions were rejected please? Did I fail to submit some required information? They are very basic and obvious vulns, which don't need any extra steps to get them to pop:

3917907
3908373

Also this one, which is a GDPR PII leak, and comes with clear instructions on how to make it work:

3917630

Thanks
