I don't really have an answer to this, but I've wondered this as well. If anything, the Operation Tiberius report showed that the corruption in certain parts of London went deep and far and that a lot of those contacts were established in masonic lodges. How they operate on a day-to-day basis is something we can only guess at and only people running in those circles are going to be able to shed light on this, but of course they're not going to do that.
