May I suggest we add an investment topic for ICOs and the like? This would be for promotional material, critism (of maidsafe and/or the project seeking cash), hype, FUD, etc.
I suggest any posts to said investment topic are visible on the main forum page for a week or two, then filtered. If anyone wants to track a specific ICO, they can bookmark it or frequent the investments topic directly.
IMO, these posts detract from the project. They are often created to generate hype and frequently not by community members. Unless we want to become a billboard for other projects, it seems reasonable to move them from the main page after their initial launch material has been published.
