Reputation? Are you talking about a reputation they gained by paying pennies to their users by logging on their website and visiting faucets? I haven't seen a user commenting on their monitoring services but most of them were just 'too happy' that they got paid a few satoshis every 60 minutes to use their faucet on their website. Do you call it a 'reputation built'?
So, you want to say that most of reviews about them are just mainly from their affiliate program users? I doubt about it. They are in business for 13 years and if it would be shady service, internet would be fool of negative reviews about it and faucet wouldn't change anything in general. If you open other forums, review websites, you'll see mainly positive comments from people who actually using this service. But probably you chose to see what do you want to see...
