Wise interview questions

My application was shortlisted after I applied through LinkedIn. The next step was phone interview with the HR. Unfortunately, I didn't make it past the HR round. But later I discovered that the HR team follows unprofessional and unethical practices. This HR has blacklisted my profile so that all my future applications bounce back within one hour. I don't see any valid reason why my application should be blacklisted. It was never blacklisted by Amazon, Facebook, Google or other companies who have interviewed me during the same period for similar roles. But this HR clearly seems to be missuisng his rights & duties.
