I'm quite surprised that the mods actually have no tools to do their job properly. I knew that there was no real reporting system in place, but there no being a punishment system either is still a surprise. No offense, but relying on the goodwill of the userbase and pushing the introduction of such tools back until shit hits the fan seems unwise and naive.
That some infamous, toxic trolls, one of them having been called out multiple times in this thread already, are allowed to act freely also points to some deficits in moderation. Trusting in everybody being friends and one big community-family sounds nice in principle, but in reality that is no way to run any large community. Blocking helps to keep personal feuds out of the comments and forums, at least as long as the feature is actually being used, but it is a weak and unsuitable bandaid for agitators like the above.
