No, the mods are not "ruining your masterpiece". It was the spamfilter, that sometimes acts a bit randomly. So when that happens again, either wait some time (we can't be watching the spamfilter every minute) or pm one of us.
I just approved your post (the spamfilter probably ate it because it was a single image file without anything else in the post, sometimes it doesn't like that). Btw, while approving your post i had to delete 6 spam posts as well, so the spamfilter has its use.
