If Ofcom does decide to pursue you, they will start by asking to see your risk assessments and policy documents, and would then in theory proceed to legal action, but in practice would just ignore you, because you're just protesting, and they have no chance of getting the millions in fines out of you.
I'm not sure what content you could put on your page, but if anyone suggests a message of support for a protest group called Palestine Action, I most strongly recommend that you don't do this, because the nature of their protests has led to their proscription as a terrorist organisation, and the resultant legal action against you would be of a very different nature.
Starting with less extreme content, such as a how to buy drugs guide, and gradually escalating to provoke a response, would be wiser.
