When creating a help-thread, we send a few hints.
One of them is how to act when no one responds. Our entry point for this hint is bad. It would be better if we post this message when the moment of inactivity has come.

So we should detect when a thread is inactive (no one except OP responded since 5 hours) and then let the bot automatically post this message. This will also lead to an "auto-bump", which may cause more helper attention.
