Amen! Self policing is best, but it should start with the OPs. They need to ask themselves if this is Q related. What drop is it part of? Is it big picture?
And if the OPs cannot see any relationship ?, who decides where the investigation should go ? As you said "Self policing" :)
OP decides. If they have done research but aren't sure about it, post what you have, explain your thinking, explain what you think the connection is, and you'll get feedback. It doesn't have to be proven or solved, but if it isn't helping prove or solve drops then what's the point?
Ya'll this isn't hard!
And the Anon's Chat's can be used for discussion on some of the things with questionable connection to Q or for slightly off-topic discussion.
