Issue with random deletions and mass spam

Hi! 

We are aware of the random deletions that have happened and trying to work out the cause of it so we can fix it. In relation to this, I know there was sent out a spam message from someone claiming to be travelling Europe and looking for friends around the 20th/21st depending on your timezone. If you received this message, I would be grateful of you could let me know when it was sent to you, what your timezone is, and whether you were online or not when it was sent. This is to figure out if the message was sent manually or not. 

Thank you!
