I agree with others - these types of observations depict organisms that are wild by iNat’s definition (assuming that the observer didn’t intentionally but the specific item at the store because they wanted to bring the hitchhiker home and check it out!). Wild/Not Wild on iNat doesn’t mean “is a threat” or “is a problem”, and whether these observations “pollute” range maps is an opinion that will vary from user to user.
Checking captive / cultivated means that the observation is of an organism that exists in the time and place it was observed because humans intended it to be then and there. Likewise, wild / naturalized organisms exist in particular times and places because of other reasons (e.g. members of native or established non-native populations or released/escaped pets, hitchhikers, or vagrants).
The ABA’s rules are intuitive in theory, but in practice are interpreted wildly differently by different people and committees over time. For example, while there is no explicit rule banning ship-assisted vagrants, in practice they are rarely if ever accepted.
