But.. What's your point?
I do not understand the policy of the forum administration. They do not prohibit the advertising of dubious and fraudulent services or companies against which criminal proceedings are instituted in different countries of the world (for example, YoBit Exchange).
Well, there's a good reason for that; most of the time it's quite hard to determine whether something is a scam, or not.
It might be unethical, there might be a lawsuit going on, but doesn't necessarily imply guilt in unlawful behavior.
With the project you mentioned it might be a bit more obvious that they're doing something wrong, still, the forum doesn't want to set a precedent. There's no court case, or a verdict, and if there was, perhaps it still wouldn't be enough to even consider banning it, because where do you draw the line then, or which jurisdiction determines what's legal and what isn't? Do you prohibit services from advertising if they have a single accusation next? Or a rogue guy suing them?
And if the forum bans one service from having signatures just because their operations are controversial, before you know it they'll need to review 100s of different companies who perhaps operate shadily. I don't think theymos wants nor has the resources to do that.
But that doesn't mean that people can't be found to be untrustworthy if they promote such schemes. You can tag and open scam accusations against them for all you want.
