Thoughts on Rubrankings.com? Lots of providers but most with no reviews.
It's another dodgy site filled with scammers. Some of the providers look tempting: Pretty young strumpets eager to give you a good time. Then all you see in their ads are just the phone numbers. No reviews, no email address, no website, and no Twitter/Instagram accounts. Nothing. No web presence. The con artists cannot produce a web presence. It's too costly and time consuming for them to attempt a fake web presence. This is the evidence that always exposes them. Stay close to TER and you'll have a chance at a real enjoyable hobby experience.
Agreed, most are scams, but there are some reputable ladies there, less than half. Be sure to google the phone numbers and see where the bread crumbs lead you. You might find a twitter account or a TER page if your lucky.
