Do we want to become a community in which the atmosphere is going to be "Everything that is not explicitly forbidden is allowed"?
If it was up to me, there would be no rules at all here. However, that would lead to total chaos, not to mention trouble with the laws (been there, done that, not going to happen again).
We want to make this a pleasant place for as many people as possible. People should be free to discuss various subjects and share different opinions. A bit of fun and games is always supported and encouraged on this forum. However, creating threads just for creating threads and posting replies just to post a reply (and add 1 to the post counter), is that what you want this place to become?
I may be taking a leap of faith here, but I still think we all have some common sense, we all are mature enough to think what is reasonable and fair. We must all understand that there are written rules that will be enforced at all times, but that there are also some unwritten rules, mostly based on common sense.
I don't plan adding anything to the rules about meaningless posts not being allowed, a fair share of meaningless posts have their meaning and purpose, but it is at the discretion of the moderators of the LR (i.e. Dee-27 & Arachne) to determine what is a 'fair share'. If you don't agree with their judgement, you can take it up with them and try to convince them with arguments why you feel that the fair share should be more than what they have determined. But in the end, it is their decision and this is not a democracy. To put it very bluntly: if you don't like it, tough luck!
