Banning those folks does us all a favor. What would you suggest be done otherwise? If you search on banned from Audio Science Review, you will find some (many older) posts but there are not many. Notably few for as long as ASR has been around. Seems more of a badge of dishonor and would make wonder more about the individual's trustworthiness if they tout. Of course, context matters as does validity. In some cases, bans are claimed but may have been temporary or simply a misrepresentation.
I have been working on how to identify those who might have more unique opinions. If have banned anyone showing potential, would be a sad day for me. However, some may be very frustrated or caught me on a bad day. In this case, would hope they would appeal to Amir. Yes, this assumes that these individuals act fairly rationally. If not, admittedly they may unfortunately get profiled with the more unsavory types.
Am pretty comfortable with our approach of only banning the truly obnoxious or irrational. If they do not have some respect for ASR and its members, admittedly will be more difficult to allow a disruptive member to remain. Those who show willingness to work through issues have the opportunity to remain members. This is because we do not otherwise ban someone before being warned or interacting with them to work through initial rough spots.
Aside from some more formal probationary member screening, not sure what else could be done. You seem to suggest that we should not ban the misinformed and would hope that this is already supported. However, many more subjective members want to post opinion incessantly and that gets major pushback from the more objective-oriented members. Drowning in the sea of objectivity, some resort to lobbying in one or more threads. The worst of this activity gets labeled as trolling.
I do think we might improve new member integration with some mandatory screening or orientation. Few initially read the Terms and Rules (I didn’t). All too often, am dealing with a report on a new member that barges into a thread that they did not bother to read and expects their first post to be taken as readily credible. Members have usually engaged and try to correct long before I arrive on the scene. If not some better orientation, then as Amir has requested, may need our existing members to be more tolerant. Am open to other ideas.
