I don't use Bumble or any dating app, but if I saw someone's dating profile on a platform I was already on I might just read it to learn more about it. Even if the person is of no interest to me. Sometimes people put interesting details about their personal life in dating profiles. It's probably not going to lead to a relationship, but it might at least lead me to an interesting topic about another culture to learn about.
In the case that it is in another language, I'd probably just use google translate if I'm not fluent enough in reading the language.
