@cathal Can't we show them what #LinkTax means? Collect all the host names of the web sites run by those lobbyists, and compile a UserScript replacing them by a bold red "LinkTaxed" – plus a popup whenever one of their pages is opened (window.location), saying "do you really want to load that crap"?
So those opposed could install the UserScript to not accidentally visiting there. Should bring down their counter a bit, at least – as Tax for their lobbying => #LinkTax.
