Common misconceptions

Users aren't qualified to rate sites

We realize the average web user isn't a security professional and we don't expect them to go out and investigate random websites for safety. We have an active group of experienced users who review sites for technical safety and help the average user avoid security threats. We only expect users to share their experiences with the websites they already know, because they are uniquely qualified to do that. Being able to learn from other people's experiences is the whole reason for this service.

Someone has to fall victim first before others can be warned

Someone obviously has to discover threats before they can warn others, but it doesn't mean this someone has to fall victim or even be a WOT user. We collect information from a number of blacklists and other sources to warn users of emerging threats before they have to experience them personally.

Reputations are easy to manipulate

When someone first hears about the concept behind WOT, their first objection is that someone could easily spam the system with tons of ratings and rate down their competitors or otherwise manipulate reputations, but that's not true. We designed the reputation system to be as fair as possible and very resistant to manipulation.

Ratings aren't equally reliable

Usually in reputation systems each rating is weighted equally and reputations are computed as the average of all ratings, which makes them extremely vulnerable to automated attacks. Therefore, we decided early on to value ratings by their merit and use some of the principles of Bayesian inference for combining the ratings into reputations. Without going into details, the system analyzes each user's rating behavior from several aspects in order to determine their reliability. When you start using WOT, your ratings have little weight, but if you keep rating sites consistently, your ratings will be considered more reliable over time. The meritocratic nature of the system makes it far more difficult for spammers to abuse, because bots will have a hard time simulating human behavior over a long period of time.

Note: User reliability is determined using statistical modeling and doesn't depend on the number of ratings or whether you agree with other users. Specifically, it's not related to your activity score or user level, which simply tell you how active you've been.

Unusual behavior is automatically detected

In addition to weighting ratings differently based on statistical analysis of user's rating behavior, we also monitor for unusual rating activity. The system is capable of ignoring spammers without human intervention and almost every type of unusual rating behavior can be detected. We investigate all suspicious activity and ratings from someone abusing the service will be silently ignored.

But I don't agree with a reputation!

The site's reputation tells you how much other users trust the website. If you disagree with a reputation, it's most likely not because the reputation is being manipulated or there's a conspiracy against the site, but because other people simply don't agree with you. Their experiences may be different from yours, it happens sometimes. You may want to start a new topic on the forum to discuss the site's reputation or if you suspect unusual activity, report it.

Ratings vs. comments

Ratings are often confused with comments, probably because comments are so prominently visible on the scorecard. Users can rate websites on the add-on or on each website's scorecard in four rating components. Ratings are private, which means they are not shown to other users. Reputations are computed only from ratings.

If users want to share additional details about their experiences, they can also write comments to scorecards. Comments are purely informational and have no effect on the reputation. Comments can be voted up or down depending on whether others agree with them. Comment votes only determine the default order of comments on the scorecard, they won't affect the site's reputation. If a site's reputation rating is determined to be controversial, comment voting is disabled to prevent one side from suppressing opposing views by voting them down.

Why can't I see how others have rated a site?

It's always been WOT's policy to keep user ratings private and have a secret ballot. If users want to reveal their opinion of a website to others, they have an option to post a comment. If all ratings were public, users might be reluctant to rate certain sites, because it would reveal to everyone they have actually visited them. Not to mention that users with an opposite agenda might start intimidating others to change their ratings. This all would lead to less ratings, which leads to less reliable reputations. Something nobody wants.

Why don't you show the number of ratings?

Unlike it might first seem, the number of ratings won't tell you the reliability of a reputation, and showing it could in fact be misleading to users. It would be trivial for a spammer to rate a site multiple times and thereby make the reputation appear to be reliable, for example. This is why WOT shows you the confidence indicator instead (the small human figures next to each rating symbol). The confidence value tells you how reliable the rating system considers the reputation and it's based not only on the quantity of ratings, but also the estimated reliability of the users who rated the site.

Why don't comments always match the reputation?

A site's reputation is computed from ratings, not comments. Leaving a comment is completely optional and since users who disagree with the reputation or otherwise feel strongly about the site are more likely to also write a comment, it's not uncommon for comments to appear to contradict with the reputation.
