Does this count as spam?

Sometimes someone will post an otherwise on-topic message with a link to an essay-writing service. I personally think links to services that enable cheating should be considered spam regardless of the message they're in. Admins: Should I report these posts as spam?

Example:

http://www.online-literature.com/for...00#post1156100

Absolutely, it's very sneaky spam. Thanks for bringing it to our attention, and of course you can always report a post like this. But no need to report multiple posts by the same spammer :)
