The problem with any statements, even humorous ones, is that they can sometimes be understood as the complete opposite, taken out of context, or not understood to be a joke among friends.
Your best bet in situations like this is to PM any moderator, including @jess, @nica, @Pipcrawler or me (@pipstradamus) about any flags you receive when you have questions about them. We all have the power to put those posts back if you explain your side of things. Randomly flagging other members helps no one, and could potentially hurt your status in the community in the future if done inappropriately.
But yes, moderators can see who flags a post. That's a benefit for us because we can see the members who are taking an active role in keeping the Forums clean from inappropriate posts, while also allowing us to see if any members are flagging for questionable reasons (such as retaliation). However, flagging information is never shared outside of the moderators team. Members can rest assured that flagging is safe and completely anonymous to the rest of the community. If it wasn't, the idea of community moderation would disappear, and more problem posts would exist for longer amounts of time out in front on the community.
And we're absolutely all about humor. It's one of the founding principles of our existence, to "crack as many corny jokes as possible", while teaching you about the basics of forex trading. So just touch base with us whenever you have an issue.
