I think you’re right! Also “contact me” would probably contain て下さい or friends…
On top of that, isn’t ご~致します double keigo? (which is gramatically wrong) I thought one would either have ご or 致します but not both? … but maybe this works differently with suru verbs (walking on veeery thin ice here )
Anyways, it’s probably best if you shoot the team an email at hello@wanikani.com.
Well, I mean, it’s basically that if enough people make the same mistake it stops being a mistake. But they do say that since it’s technically an incorrect usage of keigo that you should be aware of that and be careful if it seems like the person you’re talking to cares about that kind of thing.
