How often do you flag questions/answers? Does it drive the mods crazy when someone flags everything that is not up to Fluther standards?

I flag a lot of stuff throughout the day.
Every time I do it, I can’t help but imagine whichever mod happens to be online when my flags come through saying “jeez Neffie, get a life.” Although, I have NO idea if you can actually see who flagged it. Just a guess.

So. Do you flag a lot of posts? Questions or answers that aren’t really Fluther material? Spam? Trolls?
Do you ever think twice about flagging something?
