i don't see why it would be impossible to engage in detailed and personalized conversations with scores of subscribers? a one-on-one detailed and personalized conversation might require half an hour, and if you're an extraverted person you can probably spend ten hours a day doing this, which is a score of people every day. in a 28-day month you could then engage in detailed and personalized conversations with 560 subscribers, which boosts the number from 'scores' to 'hundreds'
if you're talking to them in some kind of textual instant messenger, rather than over the phone or video chat, you can probably maintain two to four detailed and personalized conversations at a time, which would boost that number into the low thousands
you're just conversing with people, not fucking them, and there are in fact real-life prostitutes who serve scores of clients per month
still i'd probably agree if ball had said 'thousands'. but 'scores' sounds easy
