Absolutely - I'm coming from the assumption that they are given a list of reasonable instances (for example from the kbin front page or from recommendations).

Among a curated list of servers, it's probably best to join one without assigning too much importance to it, and rather change instance later should you be unhappy. But of course, some instances should not be considered, and some might prefer to join an instance with stricter/more lenient moderation right off the bat.
