Indeed 18+ would be good, some people have young childeren. I opened a vew times this site, first thing we saw was porn related and i recieved questions about it. Also from the place I work with disabled childeren were asking questions
Sorry @Duckface I misunderstood... you want to avoid it rather than search of it. There's one for the books.
There shouldn't be any strong adult images on the blog as they're not allowed. Also I'd suggest it may not be wise to come here in work situations. If you're using the work wireless they can log the sites you visit. Even if they don't, you should be working rather than browsing if you're in charge of kids. Beats me how you can. I don't have any downtime whatsoever with a class of 25 demanding tykes.
