Your default userpic is viewable throughout the LiveJournal site, and unlike individual journal entries, it cannot be hidden or protected. It is potentially available to anyone on the Internet who randomly browses the site. Therefore, we require that your default userpic not contain anything too explicit. In particular, icons which contain nudity or graphic violence tend to be inappropriate for default userpics. Strong language on an otherwise appropriate userpic generally does not make the userpic unsuitable for a default userpic.
Non-default userpics can contain images which are more graphic in nature, and the Abuse Prevention Team
generally will not intervene if a user is posting with a graphic non-default userpic. If you are receiving comments with a graphic non-default userpic, you may wish to delete the comments; similarly, if graphic non-default userpics are being used on community entries, you should speak to the community maintainer(s).
Note that anyone can see all of your userpics at http://www.livejournal.com/allpics.bml?user=exampleusername
. If you have questions about the acceptability of your userpics or you would like to report an inappropriate default userpic, please contact the Abuse Prevention Team
