I am part of a small specialist online technical community. We just moved it over to a Hetzner box in Germany and someone there is paying for it instead of it being hosted in the UK.
If you live in the UK and can still be linked as an operator/organizer of the site (or if it's not you, other UK residents), can't they still come after you directly? I don't know about you, but I don't think running an online community would be worth huge fines to me.
