I used to enjoy the accounts on the old UK-based TimeshareTalk site, on which I served as a moderator, concerning similar and well organized efforts to publicly shame Sunterra, a previous incarnation of Diamond Resorts, over their sales practices and lack of exit ability in the UK. In that fight, there was a website set up, which if memory serves was sunterror.com or sunterrorized.com. Then some of the activists bought an old ambulance which they repainted with anti-Sunterra slogans and called it the Scambulance. That was used as a prop for public demonstrations outside Sunterra sales venues. About the time Diamond took over Sunterra, they found a way to buy out the leaders of the protesters. Many owners who had qualms about Sunterra initially thought Diamond would not be so bad and in the beginning there was lots of happy talk on TimeshareTalk about the new owner Diamond. UPDATE: In thinking more about the anti-Sunterra website, if memory serves there were two of them, the first Sunterror.com (or might have been .co.uk) and Sunterra did a deal with the owner of the site to take it down. The second which stayed up longer and the owner of the site was affiliated with the protest group and had more far reaching demands was Sunterrified.com (or .co.uk) and its start page featured a snowman melting in the sun.
When I was an HOA president, I heard a rather creative way to force a deedback. My own HOA was always willing to allow deedbacks because we found that cheaper for the HOA than a foreclosure and it got the week back where we could hopefully resell it much quicker. Her HOA felt that if you started allowing deedbacks it would snowball. She told me of one member who threatened to deed their timeshare week to North Korea's dictator, mail it care of one of their embassies and get a post office certificiate of mailing to prove delivery. Her HOA caved on that one.
