Web of Trust is a community ratings extension for FF and Chrome that allows users to rate sites for malware, spame, phishing, child safety, and trustworthyness. Used by millions.
More than likely as the result of interested parties' wanting to silence and stifle the vape community, CASAA has an "orange" rating, meaning it is borderline not cool to go to. If the rating drops more, to red, users will be sent to a warning page upon loading the url, which means effectively none of these people will even go to the site, much less trust it.
More than this, the poor rating shows up in all search engine results and links on FB etc, and most will simply not click links that are not green-rated.
So... sign up for WOT and give CASAA a good rating (you can easily find it searching for WOT in Firefox and Chrome addons)
