Yea it's a hard one to pick since at face value it might just look like a couple of teens having a good time but there are some tell-tale signs.

'Romeo's' boys aged 14-18 are the ones who go out and romance the girls, might see a few of them around, they'll be sober, it's all about getting the victim (underraged girl) hooked on drugs, so if you see one girl fucked of her head surrounded by slightly older sober boys that's a sign.

They also have there 'Daddy' typically much older like 40, they're the traffickers, they supply the drugs and money, so if you see some wasted 14yr old clamouring for there Daddy even tho it's clear there not biologically related that's also a red flag.

Last the victims are typically the most vulnerable in society like the disabled, might be hard to tell if that person's genuinely disabled or on drugs and those people are just the carers, but you'll know it in your gut if you see it.

100% report it, people don't report suspicious activity enough, could be wrong, could save a life but it IS around. It's also really sad for the victims as being in Southport sometimes the Police just brush it aside like just another junkie so you (a random bystander) might be there only hope xo.
