myWOT has a select few elite super users, as per
this link, at which the following picture giving stats on 'SuperHero58' was found;
and one rating by one of them counts for something like 100 'normal' ratings.
It's all spelled out in one of the above link.
Either that, or they can rate 100 different places at once.
As per the picture taken from the link, SuperHero58 is one busy scavenger.
And these 'super users' can wipe out 'normal' ratings of contradictory nature.
So yes, it is being 'gamed', no question.
Besides that, myWOT is trying to 'monetize' and get financial sponsors, and the whole thing is becoming 'bought & sold'.
Also, at the above link, the guy complaining and revealing all this, had his website given a negative score.
So he ran a 'test', not to do it, but to prove a point; he posted an offer to pay anyone who could reverse his score ratings, and he got offers from at least two different people who promised that for X-dollars, they would put their multi-bot myWOT memberships to work pumping up super-score positives for his website.
Is my reporting fair enough?
Check the above link; you'll find it all spelled out there in all its glorious detail.
