Googles John Mueller said you can overlook hazards and blackmail emails from individuals who demand do-follow links. John stated on Reddit when asked about these risks “neglect it, its simply spam.”The email received by this individual included this hazard: … If I do not seeing a backlink in one week, I am create million harmful blog remark spam and redirect backlink to and you can biding farewell to your Google rankings for 1 year or more.I trust you making appropriate decision … He asked, what can he do about it?I assume most of you who get these e-mails, those e-mails get caught by spam and you do absolutely nothing about it anyhow. But if you do get those e-mails, just erase them and do not stress about it.At least, that is what Google suggests and has been for many years and years.Forum conversation at Reddit.
