Yes. Please do. When I 1st opened my account here I saw a regular user here with that type of message on her homepage. Honestly I was surprised if people would even go to that length, just to get followers/popularity. I believe in having basic good faith in people. So I never bothered with such messages. But, I understand it now that it has happened to me. The worst part is - this is the Internet. So you can't do a thing about it even if they do copy your comments/reviews, especially in an open site like mangago, where you can't restrict the viewers. They'll just say, "I made my list before you so I am not the one copying". As reviews don't get dated like the date of adding manga to a list, people can easily copy them & get away with it. The last of my measures against copying, is that message. If they still continue to do that I would have to stop updating my list altogether/open a new account for the peace of my mind.
i just happen to pass by and read your profile out of the blue... actually, i have also been worrying about my reviews being copied and such... i guess i should put up some notice in my frontpage as well.
