At a guess, with a lot of experienced SP's NOT trading because of COVID, a far higher proportion of the working profiles in London are fantascists with no real sense of the London market. These SP's are filling the gap left by absent poles and hungarians and have heard a story that you can earn £200ph offering covered service. They have to wait until the phone is good and dusty before they see the error of their ways. This element has always been out there but the general decline in the proportion of experienced SP's in the current market makes them relatively more prevalent. Given the high chance of pitching up to find a Brazilian "girl" with a deeper voice (and bigger cock) than mine I haven't booked a Brazilian since Mel in about 2015.
