Why do girls not respond on tinder or dating sites?

Anonymous
Tinder Example: I'll match with someone on tinder, send a message, but then they won't answer... Yet they stay on my matched list? Wtf?

POF Example: Well this one, barely any girls reply and if they do, the convo lasts a few responses, then they disappear. Wtf? Then you try sending them another message a few days later and they dont respond wtf is that?

Another example: Some women gave me her number off POF. We texted that evening then she didn't respond. 2 days later says she had dropped her phone in the sink and left her phone in a bag of rice. I replied, she didn't. I text her 2 days later and no reply. Wtf
