I just got one of these invites from Research Media Ltd. The email did not mention any costs so I emailed back asking who pays. Only then was I told that it was £600/page and they normally write 3 pages. My response: “Thanks, but not interested.”
I’m glad that I saw your post or I might have wasted more time on their games before I discovered that they wanted me to pay for this unsolicited exposure of dubious benefit.
