Many of the attacks on it are bogus Rated 5 out of 5 stars

WOT is performing beautifully. It is true that any ratings done by actual humans are not going to be infallible. Users should read them and keep their brain engaged.

However, it appears that there is an organized campaign here to discredit WOT and it's community. Yes, many sites have been hurt by WOT. Sometimes that is the very goal of having a community who can fight back.

What isn't included in some of the complaints here is how many of the sites are/were dangerous, virus infected, scammers, snake oil sellers, hate sites...

If a legitimate site has been hurt they can go onto the site or even contact the community and ask for reviews. There is a process and most of the regulars in the community are reasonable people who will weigh the evidence.

The bottom line is even the ratings here need to be taken with a big grain of salt.
