NEW: Since the founding of this group some changes have been made. Now, if someone is not on your friends list, all images and info go to the bottom of the profile, so if you don't want to risk coming across questionable material then just don't scroll down past the shoutouts. Also, nealdt says he is willing to be more strict on avatars since you can't avoid those voluntarily, but concrete guidelines need to be worked out first.
This is somewhat of an experiment. I'd like to collect opinions on this issue and see how many people are in support of cleaning up the profile content on AiB.
Please invite anyone you think would be interested in this.
