i have been getting almost 10 spam calls a day for over 1 year since i used my phone number in local citation, e.g. yelp. i called the numbers a few times, and they are basically bots calling for harassment purposes. those numbers change all the time. (i think some people revenge because i did not take their offer in the beginning.) is there a way to hit back? i would think that cost them money too, but for 1+ years? the spam mails take up my disk space. i have to use filezilla to remove the mail>trash>current folders every other month. otherwise, my HD would be full. is there an easier way?
