Okay, but why we don't see users banned in massive amounts for shitposting who don't wear any signature at all? For example, a good part of new users are posting complete junk, but I don't see any of them banned for just that. As I see it, the mods are shrinking from banning users (and that's good in fact) and just trying to shift responsibility to a service which is not in any way affiliated with Bitcointalk. But why would the service care if the Bitcointalk moderators themselves are not following their own "laws" in respect to shit posters. This seems to be the primary reason why services such as Bitmixer are made into scapegoats...
Oh really? You have no idea how many users are constantly being banned. But users wearing sigs are more likely to be banned and are more noticed as more people tend to report them. Those not wearing sigs tend to get a little leeway because they are not reported as much. However the staff still bans them as we see them.
