I've been thinking for a while that at some point in my life it would be nice to work for a porn site. High traffic and big challenges. Not so different from the ad or fintech, but I'd prefer porn over those two anytime.
The drawback to driving traffic is that the porn companies are constantly shaving you. You had to track each of your referrals very carefully. Though generally, if the affiliates saw they were getting fucked over, they just switched off their firehose and directed it to another porn company. That always resulted in a face-to-face meeting with apologies and increased incentive to redirect the firehose.
