Pro tip: A pretty quick and easy indicator that its a fake ad is if the only contact info is WhatsApp, Snapchat and/or onlyfans. Even if they have a phone number listed, if they are listing a whatsapp # or snapchat username as well I'd be super skeptical. If they only have a whatsapp/snapchat/only fans its 100% a scam.
I personally use Duckduckgo but if you use Google you can always image search a few pics and 9/10 times they show up elsewhere.
As for the Indian ad I've never met a legit Indian provider before to the point thats its one of the few ethnicities left I've not been with. With that said if anyone knows of a legit Indian provider hit me up.
