The rules are there to keep it safe, at the end of the day we are talking about hard earned money here, not something that should be taken advantage of. I do agree there have been countless times where I have seen things not being moderated but others have, it is inconsistant but there again nobody is perfect.
As for your post removal I doubt they would do that unless you infrindged several rules. They probably edited out the price which is what they would and should do. I can't say I agree with all the rules but i'd like to believe they are there with good intentions in mind for our safety.
I like how people complain so much on this forum. Is it really that hard just to avoid stuff that you don't like? I guess trolling is much more fun...
