No- I can't imagine that is does in any way almost everyone in this area is the same race as we are.
The only other thing I can think of is that someone has found out about our past and does not like us for that... (I am a former stripper, prostitute and porn model and my husband a former strip club manager). We left that life over 11 years ago. I don't know. I am just grasping at straws here.
Here's a thought, as I had an issue not long ago with my mail. Only themailmandidit! Argh!
Anyway, have you noticed your mail gone missing of late? Any bills that would have your personal account numbers, etc...?
Now days, and I know a guy who does this on a regular basis, you can pay as little as $10.00 for a background check on just about anyone.
The more money one wants to spend, the deeper and further back things can go.
If you were in porn, and you look now as you did then, someone could remember you and have taken the incentive to find out if they were right, by stealing your mail and doing the research.
Especially if you have stickers on your car(s) regarding your faith now. A cross dangling from the rear view mirror, etc... In other words, if you are now outwardly, in any way, different than you were then, including to some appearing to be self righteous, they could think to scare you because they have knowledge of your past.
It's a good thing you're getting security cameras for your property. I'd point one at my mailbox and front and back door as well.
Make sure they record.
Comcast has a home security program they're advertising in our area now, that lets you look in on your house while you're away.
That part creeped me out a bit, quite frankly.

Remembering the George Orwell classic, "1984", where there was no privacy because Big Brother, by law, could watch the goings on in your home through the TV, that everyone had to have.
But now days, home security seems to be a must have to combat all the evil that seems to be growing exponentially in some people.
Also, when you invest in a home security system, I'd suggest you don't put those little stickers or signs the company gives you, on your windows or in your yard.
Why forewarn some idiot what's waiting for them, when chances are they can find a way to bypass the security system they're forewarned you have?
Let them find out the hard way that no trespassing means NO!
(Also, just as an aside, if you have a dog DO NOT EVER put up that sign, "Beware of Dog" . We know both police and Judges here and they all say, when that sign appears on a private property and someone gets bit, it's the owner liability that kicks their own teeth in, when they're sued by the one bitten. Because that sign says the owner knows their dog bites and thus holds potential to be a public nuisance. Simply posting the "No Trespassing" sign, puts the ball fully in your court.
Let a trespasser find out the dog bites when the jaws clamp down.

(Then floss doggies teeth thoroughly afterward. Because taking a bite of idiot can cause all sorts of gum disease and plaque doggie doesn't need to suffer!

)

I wish peace to your house and all this scary stuff you've suffered thus far becomes a thing of the past.
