Why is my question invisible in the R&S section after 5 minutes even?

I fixed it for you.

Some questions and some answers get caught in the spam filter and end up only visible to the person who posted them. For questions, moving it to another category for a few seconds, then back where it belongs, usually gets it to clear the filter and become visible. If that doesn't work, an edit or adding an update should do the trick.

For answers that don't show to others, one or more edits often fix that problem. Occasionally posts won't show even after several edits. The points (+ for an answer or - for asking a question ) are still applied through.

The Filter Flagged it for some reason

It was a boring question.

sorry we dk anything about this..we dk what u asked...if 2 ppl report something it disappears

Someone does that, I think. Just switch the category to another category and then back to R&S.
