I have only ever dated people I have met in person, but I did briefly attempt otherwise. I joined a dating app for about a week before I uninstalled because I found reaching out to people awkward. I joined a Goth Dating Facebook group and in fact three people reached out to me and none were goth.
I am not against dating non-goths (none of the four people I have been in relationships really have been), but it was perplexing why they were in that group and they were really annoying to boot. Yes, one of them was the hollow Earther who told me this after I mentioned what I was in grad school for.
