I sent a note to FT through their "contact us" page, regarding a watermarked image of mine I found today.
They reply saying I should contact their copyright department, and gave me their email. Why don't support forward the message to the appropriate department?

Perhaps if you send it you'll get a support ticket number for use in following up whereas if they forward it you'll be unaware of what's going on and not be able to follow up directly? I'm guessing copyright issues are something they want us to handle directly with the correct department rather than the generic "contact us" department. If that's the case they should include that info on their contact page.
