My question was deleted as I was editing it!
That's frustrating, was it automatic? Am I allowed to try and start another question to ask it?
Please see the help: https://english.stackexchange.com/help/roomba
There are several criteria for automatic deletion. Your question was removed for the reason "RemoveDeadQuestions":
The Community user will automatically delete old abandoned/dead questions in the following circumstances:
If the question is more than 30 days old, and ...
- has −1 or lower score
- has no answers
- is not locked
... it will be automatically deleted. These are termed "dead" questions.
I guess that the question was downvoted today, perhaps as a result of being bumped through editing. Once that downvote was received, it would have been deleted whether or not it was closed.
The script which does it runs around midnight GMT, with other automatic cleanup things like the rogue voting reversal script.
You can ask it again, but please make sure it's on topic.
