Vivastreet has become a parody of itself. It was bad but barely usable over five years ago. Now it's 50 fake profiles for every genuine one
That's more than hyperbolic.
Even now, given the hundreds I've checked the last few of months across London I've seen at most 6 b&s (reverse image search identified stolen pics) for every likely "honest" ad and that's only because I was skewing my search to Latinas, rare Brits (any ethnicity), Thai and Polish and barely registering the Hungarians, Bulgs and Roms (nearly all real pics, say 4 ads per dozen). Even adding in the Chinese, "Japanese" and "Korean" that are almost 100% b&s added perhaps another 4 ads per dozen checked.
I"ve had perhaps 2 (both "Indians") asking for deposits on arrival to get a door number, just went elsewhere instead. Visible male security less than 20% of the time and none caused a problem, even when I walked (much of the time). Being harsh the only other "fakes" might've been the ones that never replied to an enquiry, maybe 50% and very little subsequent spam and maybe 1 "you wasted my girl's time, gimme money or I hurt you" out of the blue with no discernible connection to a given ad, the other half got some reply and typically an address, mostly for known brothels, roads and locales where punts reported by other UKPers and next to no actual crimes of robbery or assault. All areas in the punting grounds of several contributing UKPers if not more.
A punter being (overly) paranoid does not a crime make.
