It doesn't matter how many bettas or how knowledgeable a member is. If s/he doesn't follow forum rules, then s/he will receive disciplinary consequences.
That's nothing. LolI was on one that said 10 gallon minimum. I’ve had betta for 25 years, none of them get a 10 all to themselves 😂
I like longer finned fellas who I find do well in smaller tanks. Just my opinion though.
