Yeah, in the past few months I have received zero messages, but several guys a day "like" me. At first I would check out their profile and send messages to some (although most, well, it was obvious they hadn't read mine. Their profiles were pretty much a list of everything that wasn't me being what they were looking for).
But I never got messages back, so now I don't bother. If they actually want to talk to me, they'll have to send a message, not just "like" me. Frustrating though. Several of them a day and not one willing to send even a couple sentences.
