So pay with LTC or XMR instead? There are plenty of high liquidity coins with low transaction fees, these are just a couple examples. If the alternative is to not cam at all it seems pretty obvious, even if you are unbanked and get hit with 7% fees from an ATM or crypto-fiat in person moneychanger. It's also trivial to exchange BTC to LTC (or other low fee coin), you don't even need KYC or in some cases to even use an exchange (atomic swap BTC-LTC). So the cam girls could take fees in LTC and then swap them to BTC once they have enough value to be worth the transactional costs.
