Oh come on drop all pretense already. Everyone is posting on this forum for their financial interests only. Users, mods, admins, the whole package. It doesn't matter if you have more green than the Brazil national flag. This forum is one gigantic artificial advertisement and nothing more.
I dare to disagree. These siganture campaigns in the forum should be treated as a reward system for actively participating and contributing something valuable to the forum itself. It is not solely for financial interests but rather an exchange of ideas and thoughts, a way to learn more and effectively especially to those who have experienced it first hand.
To OP, you can choose to ignore, report, or blacklist them. Signature Campaign managers are implementing strict rules and choosy in picking participants because they knew about this. Maybe some are not that strict enough particularly in the ICOs which have hundreds of participants to look at it one by one.
