Why do contributors delete their own posts?

“I am not a troll.” 🤥

Denial, always the first sign of you know what.

If the point of posting is to contribute to a thread, then why delete the post? Are their actions regarding their contribution is that such posts are somehow time-sensitive and having only limited value that warrants deletion thereafter?

I’m not interested immediate responses; those who post and delete their post shortly thereafter are only interested in immediate responses.

I’ve had some of my posts deleted by the moderator. No explanation is ever given!!

You can not (rpt not) tell who was responsible for deleting a given post. That’s one of the subtleties of the system. 😬
