The biggest problem I see is bad moderation, thus basically agree with Matt’s supposition 100%. You should at least be able to send the individual an email with an warning, or explanation of why they are blocked, banned or marked as a spammer. I even took the time to email and ask the ptb about getting booted and if it was maybe in haste?
Basically, if you disagree or present an alternative thought pathway, you aren’t welcome here. Oddly, the limiting of ideas by banning folks off the cuff is exactly the opposite of allowing a multitude of ideas as james professed while allowing a political discourse and professing his love of Trump.
Again, bad moderation is the leading cause of IDO become a closet.
