In Chat rooms, users are able to edit and delete their own messages within 2 minutes.
Here, this feature is misused by some users. They often self delete messages which provide context to the conversation. I have seen many moderators and Room Owners saying some users not to delete their own messages which provide context to the conversation had. Deleting also confuses the future readers. The confusion is whether there was something wrong happened in the chat (Generally, conversations of a single user are deleted when rude flags were raised on their messages). But in this case the flags and mods are not involved.
From my experience with moderators (not warned by them), this is not a good practice to follow. Is it a good practice to do so?
What can we do about users who often self delete their own messages unnecessarily and misuse the privilege of self deletion?
