That usually happens when you have been overposting, probably due to a glitch on AnswerBank, and your account gets banned - all posts disappear.
When the glitch is sorted and your account reinstated, all the posts show again.
Or several people could have reported your post, which means it is removed until a moderator can assess it. If the moderator sees nothing wrong with it, it appears again
i havent been overposting so its not cos of that, and i dont see why anyone would report it as the 2 questions where- can you get spice from flowers? and what does the code mean on the back on a dan brown book? so easy questions and not likely to upset anyone.
Some people on here are very easily upset, but most likely to be a technical hitch , same thing happened to me a while ago. I wouldn't take it personally
