Where both sides have to conform to a very strict etiquette (platform rules), until they both decide to move their relationship to next level anyway. I can see how it can appeal to some people.
Why would you choose to not have information about the other party, when you are trying to evaluate them?

You start by sending messages, establish a relationship. Then you elevate it to messaging/calling via other platforms or real world meetings at your own pace.
It's not for concealing that you're a dick (well, it could be), it's more for protecting you from who knows how many people with who knows what intentions. It's not a guarantee, but it's a filter that works fairly well.

I have no idea either, but suspect part of the answer is "frequently"
