Why do questions not show up sometimes?

Because this site is glitchy, just keep reclicking on it until it shows

When using mobile for access, some symbols will cause a question not to appear, especially the % symbol. Write out "percent" instead.

Some links will also trigger the filters. Try posting without links, and then adding them.

Some do appear, but are violations that are immediately caught, reported, and vanish.

Since you are a level 1, you are only allowed 5 questions per day, after that "false" appears. Wait until after midnight Pacific time to try again.

Thanks to all of you for your answers

It a conspiracy.
