That thread title can easily accommodate a simple CAPTCHA, a computer program or system intended to distinguish human from machine input. If you are still within the edit time, go ahead and put in a simple (but incorrect) math equation. such as, 4+5 = 7 That would achieve one of two things: 1. fix the empty space with something that goes well with the title of the thread. 2. you might think that this math problem is sillier than your original, and you might input the original back.
