What to do if you suspect you're being stalked
Tony Neate, CEO of Get Safe Online, tells Sun Online: “The perpetrators commonly obtain details about you via online information of personal and financial affairs, social and work life, relationships and your location.
As a starting point, ensure only the minimum information about you is available online and take stalking seriously.
Report it before it has serious effects on you and others and keep a record of all that takes place so you collate evidence whilst it is happening.
