unwanted messages, how can I delete spam?

Hello, how can I delete unwanted messages in my thread? See last post on my „365 days - 365 songs“...
It comes from member „selecta“

Thank you for help

There is a little triangle (traffic sign warning) in the bottom left hand corner (just above the + Reply to Thread button if the message happens to be the last entry. You can flag a message up as spam. I already did this on your thread, but I suppose that it will get higher priority the more users flag it up.

Many thanks, dear Ms Bean
