So how else I can use those reward points ?
I'm just saying the way you did it matches a pattern bots have been using recently so our detection system automatically blocked your accounts.
Ok, then once again - what is the point of reward points system if you can't use them because the system detects it as abuse/bots/something else ? The solution would be to lower the limit of encashing reward points, but I'm pretty sure that won't happen.
Did you link your wife and your account to different IP addresses or mobile phones? or are you using this faucet for both accounts on the same IP address? Wetsuit do not have a problem if more than one person in the family use his faucet, but he wants them to register that under separate mobile phone numbers.
Nothing wrong with it, when the family wants to join in on the fun, but you just have to inform them that it is not multiple account abuse.

The system is not perfect, but it will detect & block multiple accounts.

Yes, we use different IP addresses (I work from home, so it's my IPS address and she uses her carrier's one). When I'm out I also use carrier's IP, but it's dynamic, so it should be different every time I connect. Also, I don't think it's possible to claim from the same IP address, even on two separate accounts, right ?
I know the system is not perfect and there are botnets or other kind of stuff that's making regular users' life hard. That's why I'm not angry or anything. Just trying to resolve it the right way.
