Having that much referrals sounds impossible these days because the number of faucet hunter is not as huge as what we can see in the past. If he has that much, I believe he did it since long time ago but the question is "are all those active referrals?".
It is useless to have hundred or thousands referrals if they are inactive. It applies in all kind of services where the commission will always depending on the activities of the referrals.
Coming up to where to promote referral link? There are many ways as mentioned by most other users here. Social media can be a good choice if we have many friends/followers. Other way can be on forum, there are some other forum outside bitcointalk where referral link is not something against the rule.
