No. I at least address just about everything I get, unless it’s no longer relevant to current events (and that hasn’t happened since the night I chased after Sweetie Belle and Scootaloo).
I have no questions right now, so if I didn’t answer, I didn’t receive it. Which sucks because there’s no way for you to know if I have received it!
I hope they fix this stupid bug with tumblr failing to deliver questions soon. I’ve had several here recently that I’ve sent that didn’t make it through.
