Facebook censorship is not something that I have ever experienced over the plethora of Facebook motorbike sites that I inhabit. Mostly their censorship is an urban myth when applied to our kind of sites.
If they censor extremist, racist, abusive sites then I have no problem with that as I do not sign up to those kinds of sites.
As a result of what is now the IKBA site I have met many great people, yourself included, it has indeed expanded everybody's circle of friends and I love the format. However Facebook has a place in the classic bike world and I inhabit that world as well. At least on there I don't get pop-up ads.
