I use http://clutterersanonymous.org almost daily to look up meetings, keep up with events, and familiarize myself with with the program. It is a fine recovery site, safe for anyone. I trust it completely. I have scanned my system for malware after going there and there is none.
The negative comment was from 2012 before the organization Clutterers Anonymous purchased the domain. Now that it is owned by the organization, it is populated with content specifically related to the 12-step program. While the site is not designed for children, there is nothing unsafe or untrustworthy on this site. It is a reliable resource to the people who need it and provides accurate information to those who wish to learn more about the problem of and recovery from cluttering.
The poor review is from 2012 and describes previous version. Site has been revamped, new domain name (org not net) and is overseen by a reputable group of people and professional webmaster. I go to site frequently, am member of org, and totally trust this site. Org is unable to expunge previous site from web due to lack of cooperation with former host and Google.
