Anyone using a bot to claim the hourly free BTC is abusing the site; and that's the reason it's unfair for the rest of the users.

Take freedoge.co.in as an example; same owners, "same" project, but different crypto. "A few" users started using bots to claim on the site; and as a consequence, the minimum reward was drastically reduced (that's how it's unfair for legit users), and eventually the faucet was disabled.

An average person can make between 8 and 16 claims every day if they have enough time; 340 satoshi/day if all 16 hit minimum reward. There will be some days in which you can claim more, others less; so it's pretty close to imposible to roll 16 times a day for a whole month (340*30=10200 satoshi). Now, if a user is using a bot to claim 24/7; (21*24*30=15120 satoshi). Faucet bots are getting 150% of what a person having tons of time could get every month. With current BTC price, this may not seem a problem at all (after all, 5k satoshi isn't that much), but some years ago; when you could get 600 satoshi/hour; things change a lot. Not only that; every roll gets lottery tickets and reward points; and the referer gets a 50% of every roll, with daily interests paid if the ammount is higher than 30k satoshi (+ ref comission).

Faucet abusing is not really about the number of satoshis they can claim; but about the damage they do create indirectly.

Dice bots, on the other hand, are allowed.
