Scamsters galore

Do you feel companies are using contact information of candidates (from job portals) to spam the hell of out of them, thereby bloating their own lead CRMs with the same? In my case, recently I've received calls from Pristyn Care, Unacademy, Vodafone, upGrad, other BFSI majors, etc. Having said that, I don't discount banks and fintechs as well.
