Sorry for the problems that you've had. The spam filters work by finding certain words in posts that are frequently used by spammers; many of these would be obvious, but some are less so, and sometimes they make up several letters of a longer "innocent" word. It's likely that some of these were in your post, unknown to you, and triggered the filter. Once you've made two posts (which you now have), the system should leave you alone for future posts.
Another recent member from Australia had issues with banning and site unavailability; if you'd like to PM your IP number to me, I can check to make sure it's not part of the "banned list". Sometimes these things don't quite make sense to us either! Again, sorry for the problems you've had, and we'll do our best to get things in order.
