Hi @Jianye, yes, I’m afraid it is gone for the moment. We had a lot of trouble with people accidentally deleting their own posts, so I asked our technical team if they could add a confirmation message asking people if they are sure they wanted to delete. However, unfortunately, this turned out to not be very straightforward from a technical point of view and could take some time. Given the high rate of accidental deletions, and the serious consequences this can have for people getting support, the best way to prevent this at the moment is to hide the button. I’m afraid you’ll have to request posts deleted by admin until we can find another solution.
We didn’t have an option for users to delete their own posts at all until last November, so we are only reverting to how things were on the site for many years.
With regard to private messages, yes, admin have access and can delete them if requested. The community guidelines do apply in private messages and we have access in case an issue is reported - for example, abusive messages sent privately. However, it is our policy not to read private messages unless an issue is reported to us, in order to respect user’s privacy (as stated in our terms and conditions: Terms & Conditions)
