Thanks! Glad it was helpful!

There's a team called @steemcleaners who are doing an awesome job of identifying and downvoting spam posts. If you're not already familiar with them, you should check out their work. They also have an abuse reporting form here where you can report spam posts and have the accounts creating them notified of the infraction. It's handy for larger SP accounts where you might fear retaliatory downvotes for doing the dirty work personally. SteemCleaners also rewards you with a small amount of SP when you make your reports.

Also check out my reply to jhonysins in the comments of this post for a good laugh.
