Question: MaplePrimes deletets my question! Why?

I just got an email saying a maple primes moderator deleted my question as 'SPAM'. It was not remotely SPAM but a strraight forward question about how to determine lengths of lines drawn in Maple Sketcher. 

The email tells me and gives me a link to 'contact' but it's not clear which of the many possible contacts listed to use!

Here's the email:
