Spam
Quite a few members received a spammy message from somebody who joined just to post spam. Others may have got an email notifying a new k9 mail, but it wasn’t there when you logged in to look for it.
That was because the offending account was deleted, and all the messages they sent went with the account.
It’s a bit of a cat and mouse game, but we will do everything we can to stop spam and spammers will always be removed from the site
