The site is primarily focused on London/UK biking enthusiasts.

> Make a forum that is only for UK users

That is the forum for UK users.

> Just ignore the law and fight it

The linked post mentions that the fines for failure to comply start at £18 million. I'd understand not wanting to take that risk.

> Setup the forums on bulletproof hosting which ignore such silly laws.

I think this is the most viable strategy, but even then the site owner incurs risks through ie. ownership of the domain or considerable participation.

£18m is a maximum, not a minimum, but your point stands.
