Over the years I have noticed a disturbing trend here on DakkaDakka. The professionality of the insults is growing rare, refined taunting replaced by crude slurs. Inevitably these poor attempts at ridiculing others end in suspensions. This is naturally depressing for any civilised poster to behold. A community is only as good as its E-bullying, after all.
So, I ask you this. Have you ever wanted to really piss off that annoying guy, but in a way that only he will understand and thus won't invoke the moderators' wrath? If so, read on, and I will reveal the secrets to becoming a paragon of passive-aggressiveness and implied insults.
Step one: spelling
Spelling is often key to proper passive-aggressive posts. It can make the difference between the post being perceived as a compliment or a blood-boiling insult. Two things are central here. The first is to
never capitalise, and the second is to
rarely, if ever, use punctuation. To bystanders, it will appear as though your spelling simply is poor, but it will give your targets hints that something is amiss.
Step two: emoticons
Emoticons are not strictly mandatory, but skilled use of emoticons can turn a post from annoying to infuriating.

is rather lightweight and safe to use, but an experienced poster should consider the more powerful =P. Of course, (: is the classic and excellent in most sitautions, and it will go a long way. For special occasions you can even use it in italics (
(: )to add a little hitting power, but do not overuse it, or it loses its edge.
Step 3: composition
The composition of the post should be tailored depending on the target. After all, it should seem harmless to everyone else. So find out more about the target and design the post appropriately.
Example:
Target is infamous for thinking tanks in sci-fi should be heavier
'i can see your arguments carry great weight, so it is with a heavy heart that i leave this thread (:'
This should suffice. many fortunes to you, and lets hope none of those annoying off topic
peasants come here (:
