Second Skin is built on a third party platform, i.e. we didn't build it entirely ourselves. Unfortunately the platform that Second Skin is built on doesn't allow users to delete messages.
We are working on upgrading the site to allow for, among other things, the ability to delete messages. These features won't be available for a few months, but as soon as they are we'll let you know.
What to do if you are receiving rude/threatening messages
Contact the Second Skin team immediately using the chat feature:
If this is a first offence, we will temporarily ban users who engage in this behaviour as a warning.
We will permanently ban anyone who continues to harass other users after an initial suspension is lifted.
