Sadly the automatic consequence of automatic spam is automatic moderation.
IBs never make money (not even 4chan and 8chan) and all run by volunteers who sacrifice their time and braincells to keep their beloved chans open. Not many people volunteer to mod an IB, in fact probably less and less. But users expect a service as if they'd run by some big corpo.
And spammers are getting more effective. Something has to be done.
False positives always be a thing.
Bernd should take a moment and think.
