Yeah, the thing is that the more you browse profiles, the easier it becomes to get a sense for the genuine ones and weed out the fakes. In the beginning I was messaging literally every girl who vaguely fit my preferred type, and getting a really shit hit rate. By the end (before lockdown, when there was a lot more choice), I got really good at spotting the fakes, time wasters, princesses, instagrammers etc, so I was messaging way fewer girls but getting a much higher response rate.
As others have said, having a personality and a bit of banter goes a LONG way. It's easy to dismiss these girls as "every girl on there is an escort by default". That might be true to some extent - but the key is that the genuine girls don't see themselves that way AT ALL, so even the slightest hint that they are being seen as a fuckable commodity never gets you anywhere. Again, this is only true of the genuine 'gems'. Of course, the escorts on the site don't give a shit about all that stuff.
