Can you share the deleted topic/post? If you are the one who wrote it, you will find a quote of it as an alert in the message box.
In general, the main reason for deleting these topics either because of rule number 1 or that all information is wrong/off-topic.
If you feel uncomfortable, make a quote for that post or use this tool[2], then submit your grievance here[3]
For my part, I did not feel that problem.
