So just found out today that one of our competitors is mass emailing a bunch of site owners who are linking to us pretending to be us and saying to take down our links or we will pursue legal actions. I'm pretty sure I know which competitor is doing this but I obviously have no proof! I had to post a message on our main site to say these emails are fake but site owners are emailing me and actually taking down our links! What should I do??? any suggestions??? Thanks!
