Oh, no, this is BAD.
There's a fine line between barbed comments and outright flames. Barbed comments do not directly insult a member, although they may indirectly.
Flames, on the other hand, directly insult a person... LoKuS, you've done it, as has johnny... and even obliviongirl herself flamed in the trivia topic. I've done my best to keep myself at the barbed comment level, and I'm prety sure that I've come close to the line, but never crossed it.
Accusing someone of trolling, by the way, isn't flaming. If they go on to describe in great detail how stupid the person is outside of their posts, then sure, it's flaming, but just saying that someone's been making useless posts isn't really insulting them on a huge level.
