I've been unknowingly online stalked for the 2 and a half years online by my husbands mistress (I only found out recently he was having and affair
But it was her odd online behaviour that alerted me).
She did it mostly through FB. My FB is set to mostly customised friends and pretty damn private but I do use alot of FB groups.
For me it's weird stuff like if I post in a local community group something like where is there a passport photo booth locally, she always replied first.
Then she would post bizarre things on local groups about xmas/birthday gifts/ideas for her "boyfriend" (My 55 yo husband) but with too much info about his life,work location, career, age etc. At the time I thought it was someone with perhaps a learning disability as there was just too much info in each post with no idea she was trying to get my attention or linking the similarities to my husband. It's only once I sussed her out and went back and did a search I found over 400 posts all hinting heavily who her "boyfriend" was!!
She also worked out where I worked by a well meaning genuine friend tagging me on a community page with some random person asking a genuine question about my workplace (that deals with the public).
I kindly gave limited info to answer this person. Then over 2 years she posted several times with "Anyone work at X can tell me what the procedure is for xyz/what time it opens/How much is the car park" etc etc. She even wrote a Trip Adviser review on me!!
It turns out she even turned up and got me to deal with her, me totally unwittingly.
She found out quite a bit about me despite my privacy settings by using time and pretending to need help on community groups. So be careful what you answer on those!!
It works both ways. I've now sussed her out and know loads about her. That was a real eye opener. Once you have someone's email address and full name and address it's amazing what you can find online.
I found Trip Adviser reviews she'd written for various hotels and restaurants which coincided with the dates my husband was so say working away.
She reviewed sex toys, is on ITV news fairly regularly for a campaign she's running, I know her Dad died, I know where her son goes to school,plays Rugby, She eats alot of desserts, goes Line Dancing etc etc. I know where she works. I know quite a few people she works with take the piss out of her a bit and I get the impression they humour her and aren't that keen.
Obviously I'm not a fan of her, but she does cone across as a bit if an oddball.
Anyway I'm going off on a tangent now, but basically it turns out she is pretty obsessed with me. She wants my life, my marriage (she's welcome to the shit husband), my house, my job etc etc. She got desperate for her married man to leave his wife and kids and after 3 years I can't blame her, but he was spinning her the age old line with no intention of leaving, so her stalking obsession led to her dropping huge hints so I'd find out but it was actually her size 18, 99p, skid marked Primark knickers she probably intentionally hid in our family car that gave the game away.
