Achievement Hunters Unite
If I may, let me share with you one more suggestion for the invisibility achievement:
Dress your avatar as somebody poor or as a lower-class peasant instead of wearing expensive, classy or cash-shop clothes. Also, avoid making your avatar look cute. This would make posters show little or no interest in you and would increase the chance of your thread slipping by them.
This tactic did work for me and to three other people who sought my advice on it years back.
Being naked also helps and posting a topic that would be boring to CB'ers.
I got the achievement by being naked and posting "SPAM". I then posted in a bunch of threads to get mine bumped to the second page.
