You can't compare Symbianize to bitcointalk as Symbianize is a local forum, and every forum has different rules.

actually I also notice that some of my local post were deleted but that reminds me that I should improve my post, a mods that is so strict will result to a better forum, but if you are confuse why your posts are deleted and you believe it's not spam or off topic, maybe you can PM him and tell your concern.
