I will never use icopress as a signature manager because I am consistent about conflict of interest and would consider it a conflict of interest due to me giving him 50 and soon another 50 merits.
There is nothing wrong if you send merits to Icopress because he's a well contributing member and he deserves to have those merits. And, I believe you can get into signature campaigns managed by him and that won't be conflict of interest.
If he's managing a campaign and others are getting into those campaigns then you can also be part of those campaigns. I'm very sure that you sent Icopress those merits because you believe that he deserves those merits and there's no conflict of interest when you send 50 more merits.
