Even a smiley eye rolling thing though, from someone who has been around for awhile and knows their ****, does convey a message and can be posted for a reason. If someone obviously doesn't put any thought into their question or comment, they can rightfully expect one of two things: no response as was wisely suggested, or a response of low effort and flame for their lack thereof.
-"Like yo, what's the best supps to get big and lose weight man?"
-"Research numbnuts/****off/Learn to SEARCH/"
Or hey, a real question just pulled from another board:
"..what's the best, most effective weight gainer out there. Something i can just get at a GNC or something."
Why, why why just fart out a question like that without LOOKING first, it's obvious when you register how many thousands of others also use the board, so if you feel the urge to call the individual on their lack of effort, why not?
And don't give me this "you'll lose potential valuable contributors by alienating them through flames and insults" bull. If they were to be valuable contributors in the first place they wouldn't spout ignorant poop to begin with.
