Is my service going through a VPN before it reaches the house?

[#1]

I'm trying to register an account here: https://swglegends.com/
I keep getting refused as they report I'm using a VPN/proxy as per some IP reputation tools:

IP Address Reputation & Risk Details:
Country: GB GB
City: Stoke-on-Trent
Region: England
Hostname: *********.plus.com
ISP Plusnet

ASN 6871
Proxy Status: true
VPN Status: true
TOR Status: false

75+ is suspicious | 85+ is high risk

I really don't know where to go from here.

@Gravlock I don't know where they get that 'information' from, but no PN connections go through a VPN (unless you have one set up). I suggest you ask how they have determined that.

Just some 3rd party IP reputation tool they use.

I'm guessing its just a false positive then.

It certainly is -and it is a site I'll never link to again, it downloaded 78Mb of data in about 3 seconds when I clicked it.
