I'm not talking about "methods". Asking to oppose or support a flag is not a problem, be it a thread or a PM, as long as it doesn't break other rules - like spamming. Refusing to do so is also fine, as we can see in BitcoinGirl's response. You're trying to create new rules that don't make any sense. We do need more DT members and other users to weigh in on disputes like that, not less.
Why make it private while we already have an open thread for asking support or oppose a flag? Why to some selective friends but not to general to everyone?
Can we ask LFC_bitcoin, BitcoinGirl to share the message, BitcoinGirl already talked about receiving PM and LFC_bitcoin admitted of sending PMs to some users.
We are interested to know what was in there that bought oppose to the flag from people who had no contribution in the topic but opposed the flag? We want to be sure that LFC_bitcoin did not tell them anything that create an alert but "take a look at the flag".
Or we just believe LFC_bitcoin and BitcoinGirl that LFC_bitcoin said, "take a look at the flag" like we believe that SP is a highly reputed sportsbet and they will not scam anyone. This will be ironic.
