From http://www.copyrightservice.co.uk:

" 1. Is a logo subject to copyright?

Yes. A logo that includes artistic or design elements, (i.e. not just the name on its own), is legally regarded as being a work of artistic creation and therefore will be protected under copyright law.

Copyright protects the logo as an artistic work. As copyright is an automatic international right, it therefore follows that, (other than activities specified under fair dealing rules), unauthorised copying of that logo would be an infringement.
2. Could a trademark also apply?

This is possible. As the name suggests, a trademark can be applied to the logo as it is an identifying mark of the brand identity. Registered trademarks are applied for within a particular country or region and typically within a trading sector. A trademark will only cover the mark within that region or trading sector.

If you are interested in a trademark, you should contact a trademark attorney or your national patent or trademark office for further details.

The differences between trademarks, copyright and other rights are discussed in more detail on our intellectual property rights page."

So this campaign might theoretically be a good idea - but might lead to a bitter end...
