Facebook ad account bots fake purchases

Just wondering if anyone has run has had a similar issue with their Facebook ads of bots from Kansas coming on my site and adding to cart and firing fake purchases on my pixel?

It also seems to ruin the ad optimisation after they get onto it.

I asked Shopify help centre and they only recommended some apps that didn't work or to put a captcha not the checkout but that will affect my conversion.

Any Idas?

I have the same problem

Check your google analytic first.
If they are from the same area - exclude it from ads.
Not sure if there is any alternative for pixelyoursite for shopify but check that out.
