You may arrive on a webpage that has a long list of websites, several hundred could be referenced in a single page and you may wonder why WOT does not display a rating icon for every site. There is a load restriction in place that is set to an x-quantity per browser.
An example of a website that WOT will, by default show rating icons, but where not all listings are loaded is DMOZ.
Currently loads reputations for at most 100 different domains on any given page - reloading the page will get you another 100 reputations.
Doesn't support non-Gmail email providers.
