Cops.
I had a stalker for a while, it was great.
No kidding - he’d leave chocolates, bags of dog food, love notes, concert tickets and t-shirts on my doorstep. IRL stalking can be cooler than online stalking, because you get stuff. 
Ok, is this strictly an “online only” stalker? If so, I think your solutions are going to be some combination of (a) changing your username; (b) stop posting; © complain to moderators on the site(s) you use.
Or are you concerned this person could somehow transition to physical stalking? Do you identify yourself on the websites you use?
Your stalker rocked.
B sounds like the best plan, thanks. And yea so far it’s online only…
That doesn’t sound like a stalker.
It sounds like a potential lover.
Were/are you married or otherwise attached?
If not, was this stalker ‘just not your type’ or ‘hideous’?
Nope, I’m not married or attached. I doubt he’s a potential lover more so just trying to feed his curiosity by being intrusive. It’s not that I have anything to hide but if I don’t know a person like that I don’t want them all in my biz…
The only difference between a typical romantic comedy and a suspense film is how good looking and charming the stalker is.
Haha so true.
If it’s on a forum, there’s also the possibility of just putting the person on ignore.
And this is one of the reasons I’m less comfortable on websites that don’t let you have more than one username, or, worse, force you to give your real name. (Fortunately, stalking is against the rules here, unlike many other places.)
…and he’s still at it… Dude is a certified creep!
Okay, I’m a bit lost.
Has he threatened you? Verbally abused you? Promised to show up on your doorstep and love you forever/chop you up? Is there any potential that his online interest could lead to threatening real-life interaction?
Or does he just post about you all the time?
If he’s threatening, start by filing a police report (so you have it on record, in case he escalates later), and then don’t engage him, at all, for any reason.
If he’s just quoting you in forum posts, you’re under no obligation to acknowledge his posts at all. Just don’t respond to them, even obliquely. If you find it too distracting to skip over his posts yourself, use the ignore feature. If he’s being inappropriate (asking you invasive questions or something), report it to the moderators, and still don’t acknowledge or respond to his posts. Or just take a break from posting for a while, as you said.
But unless you feel threatened I’d have a hard time characterizing a troll as a stalker. That seems a rather melodramatic leap to make.
^ He hasnt made any threats yet but he’s been hacking into my stuff/quoting me… This case is borderline creepy. I’m starting to think that maybe he does like me…Idk. But there are better ways to get at me…but if he doesn’t get the message, I will take it offline.
