The 'no-response response' ; is this acceptable communication these days?

Lately I have been experiencing more often no response to emails, posts, questions, etc..Family members, friends, anyone. If the answer is no, just say so, is my take on it, don’t leave a person wondering what happened. (especially on dating sites). Is this the normal response now, or is it just me? It just seems rude to me. (it would be so ironic if I got no responses to this! )
