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.

These blocks are actually for faucet abuse, not multi-accounting. However, it is always a little odd to imagine what kind of marriage consists of syncronised faucet claiming resulting in identical roll histories.
