I suppose I just think that the same kind of pragmatism that is healthy for all involved in real life personal interactions, is healthy in online communications.

Like, it's better to get to know someone through shared activities (IRL: volunteer programs, common interest groups, etc.; online: interactive gaming, common interest groups, etc.) than to base an interest on a person's apparent social identity, especially a social media identity which is by nature not so much "fake" but simply not the same as who we really are. We don't come across quite that easily, as people; we're all deeper and richer in form than what can be encapsulated that way. So for me, a person reaching out to me with whom I haven't interacted, is approaching their idea of me and not the actual me, so it's not as good of a foundation; and leaves a lot more room for misunderstanding, especially around romantic interest that has been based on only social media impression.

I wouldn't personally base my interest in a person on whether they are popular on Facebook.. which may be because I know people that are "popular on Facebook", even Facebook famous, and it's no indicator of how nice they are or of anything else, except that they use Facebook a lot.
