I’ve attached 2 pictures below so you know what I’m talking about in terms of looks.

MySpace circa 2006? Nah I reckon something like reddit would be alright. Some of the subreddits like https://www.reddit.com/r/goth/ might be helpful. Facebook could also be one, I know there are groups dedicated to almost anything for major cities across the globe try to meet people there. Clubs are also an option. In Melbourne where I'm from, there are clubs and bars that play punk, metal and garage rock, they cater towards that crowd and you should be able to find some people there. If it's a specifically romantic thing, try tinder or bumble. Post photos in your punkiest outfits and see if anyone within the same subculture might be interested.
