This rule is an absolute nightmare, shame on whoever wrote it and whoever thought it was a good idea. This rule is vague, useless, and just opens plenty of opportunities for it to be exploited.
What the hell does "being disruptive" to the community mean... that's incredibly vague and not helpful at all. What undesirable behavior that is considered trolling isn't already covered by the rules? Not being allowed to speaking badly about others? You mean, don't be disrespectful... already covered by the rules? I mean, the rule literally says not to the break rules, like come on, did anyone proof read this?
In the announcement thread, BoM even mentioned Polarzz as the "prime example" of a disruptive member, I guess as a way to show why this rule was needed. Yet all of the listed "disruptive behaviors", such as making homophobic remarks and harassing others, were already prohibited by the rules.
The whole mass banning yesterday didn't help clarify anything at all. I mean, in Caution's response yesterday he didn't explain how any of those guys were actually being disruptive yesterday. Nothing about the gif Scrolls posted, nothing about anything Creten said, nothing. He just said general stuff like "you guys were violating THIS rule" or "you guys are at this level about 80% of the time", how it wasn't "quite harassment" (so, they didn't break the rules?), and then talking about their previous "disruptive behaviors" (harassment, disrespect, spam pinging, leaking info, etc.) which are once again already prohibited by the rules.
To me, this rule seems intentionally vague as a way for higher-ups to remove people they don't like out of the community without real explanation or reason. An opportunity for BDs and others to overreach and punish behavior that isn't covered by the rules. There's no protocols to enforce this rule or anything... BDs can just slap a "being disruptive" label on you, cite that thread, and you're gone.
I'm not trying to defend the behavior of that group or others. They've broken actual rules, as I said previously. Maybe they deserved to be banned for their previous infractions. But you guys literally make the rules, so explicitly list the behaviors you don't want in your own community and enforce them. Make amendments to the list if you missed shit. Deal repeat offenders harsher punishments. This grey area "rule" littered with vague terminology makes no sense and will probably continue to be abused like it was yesterday.
