Messaging and inbox

i sent a message to someone and she never opened it either.

Can't say I disagree. Although I question why there is a 'message request' which is separate from the 'inbox'.

I'm sure there's plenty who do check.
It's the responding part they're more than likely not doing.

Most DO check their inbox in the beginning, and that's why they no longer do.

I just noticed it doesn't notify you if it's in the request category.

I was about to say that I always check mine, and then I noticed a message request from several days ago by somebody who called me a motherfucker and blocked me. I've never even had interactions with that guy, he just decided he hates me enough to tell me in a PM before blocking me.
