The only problem with pisstaking/banter on this forum is that we have posters from all corners of the world.
One man's banter may be construed as another man's personal attack. It's a fine line to judge it. Minor point I know, but if people made more/better use of the emoticons threads would be easier to moderate, and posters, and mods alike would perhaps better be able to judge a cutting one liner designed to raise a chuckle, rather than a snide underhand personal attack.
I'm as bad as anyone, a joke as opposed to a personal attack has led to me being watched, no great deal, but as a mod it was difficult to judge my offending post I presume. The mods don't know us all personally, so take us at face value.
The thing is, I know I mean't no harm, and as a result the 'warning' doesn't bother me in the slightest. It's a forum, people need to lighten up a bit, if someone tries to shout you down just walk away, it's easy. Most posters know who the offending people are anyway.
